NAME
rsnapshot - remote filesystem snapshot utility
SYNOPSIS
rsnapshot [-vtxqVD] [-c cfgfile] [command] [args]
DESCRIPTION
rsnapshot is a filesystem snapshot utility. It can take incremental
snapshots of local and remote filesystems for any number of machines.
Local filesystem snapshots are handled with rsync(1). Secure remote
connections are handled with rsync over ssh(1), while anonymous rsync
connections simply use an rsync server. Both remote and local transfers
depend on rsync.
rsnapshot saves much more disk space than you might imagine. The amount
of space required is roughly the size of one full backup, plus a copy
of each additional file that is changed. rsnapshot makes extensive use
of hard links, so if the file doesn’t change, the next snapshot is
simply a hard link to the exact same file.
rsnapshot will typically be invoked as root by a cron job, or series of
cron jobs. It is possible, however, to run as any arbitrary user with
an alternate configuration file.
All important options are specified in a configuration file, which is
located by default at /etc/rsnapshot.conf. An alternate file can be
specified on the command line. There are also additional options which
can be passed on the command line.
The command line options are as follows:
-v verbose, show shell commands being executed
-t test, show shell commands that would be executed
-c path to alternate config file
-x one filesystem, don’t cross partitions within each backup point
-q quiet, suppress non-fatal warnings
-V same as -v, but with more detail
-D a firehose of diagnostic information
CONFIGURATION
/etc/rsnapshot.conf is the default configuration file. All parameters
in this file must be separated by tabs.
/usr/share/doc/rsnapshot/examples/rsnapshot.conf.default.gz can be used
as a reference.
It is recommended that you copy
/usr/share/doc/rsnapshot/examples/rsnapshot.conf.default.gz to
/etc/rsnapshot.conf, and then modify /etc/rsnapshot.conf to suit your
needs.
Long lines may be split over several lines. "Continuation" lines must
begin with a space or a tab character. Continuation lines will have
all leading and trailing whitespace stripped off, and then be appended
with an intervening tab character to the previous line when the
configuation file is parsed.
Here is a list of allowed parameters:
config_version Config file version (required). Default is 1.2
snapshot_root Local filesystem path to save all snapshots
include_conf Include another file in the configuration at
this point.
This is recursive, but you may need to be careful about paths
when specifying which file to include. We check to see if the
file you have specified is readable, and will yell an error if
it isn’t. We recommend using a full path. As a special case,
include_conf’s value may be enclosed in ‘backticks‘ in which
case it will be executed and whatever it spits to STDOUT will
be included in the configuration. Note that shell meta-
characters may be interpreted.
no_create_root If set to 1, rsnapshot won’t create
snapshot_root directory
cmd_rsync Full path to rsync (required)
cmd_ssh Full path to ssh (optional)
cmd_cp Full path to cp (optional, but must be GNU
version)
If you are using Linux, you should uncomment cmd_cp. If you are
using a platform which does not have GNU cp, you should leave
cmd_cp commented out.
With GNU cp, rsnapshot can take care of both normal files and
special files (such as FIFOs, sockets, and block/character
devices) in one pass.
If cmd_cp is disabled, rsnapshot will use its own built-in
function, native_cp_al() to backup up regular files and
directories. This will then be followed up by a separate call
to rsync, to move the special files over (assuming there are
any).
cmd_rm Full path to rm (optional)
cmd_logger Full path to logger (optional, for syslog
support)
cmd_du Full path to du (optional, for disk usage
reports)
cmd_rsnapshot_diff Full path to rsnapshot-diff (optional)
cmd_preexec
Full path (plus any arguments) to preexec script (optional).
This script will run immediately before each backup operation
(but not any rotations).
cmd_postexec
Full path (plus any arguments) to postexec script (optional).
This script will run immediately after each backup operation
(but not any rotations).
linux_lvm_cmd_lvcreate
linux_lvm_cmd_lvremove
linux_lvm_cmd_mount
linux_lvm_cmd_umount
Paths to lvcreate, lvremove, mount and umount commands, for use
with Linux LVMs. The lvcreate, lvremove, mount and umount
commands are required for managing snapshots of LVM volumes and
are otherwise optional.
retain [name] [number]
"name" refers to the name of this backup level (e.g., hourly,
daily, so also called the ’interval’). "number" is the number
of snapshots for this type of interval that will be retained.
The value of "name" will be the command passed to rsnapshot to
perform this type of backup.
A deprecated alias for ’retain’ is ’interval’.
Example: retain hourly 6
[root@localhost]# rsnapshot hourly
For this example, every time this is run, the following will
happen:
<snapshot_root>/hourly.5/ will be deleted, if it exists.
<snapshot_root>/hourly.{1,2,3,4} will all be rotated +1, if
they exist.
<snapshot_root>/hourly.0/ will be copied to
<snapshot_root>/hourly.1/ using hard links.
Each backup point (explained below) will then be rsynced to the
corresponding directories in <snapshot_root>/hourly.0/
Backup levels must be specified in the config file in order,
from most frequent to least frequent. The first entry is the
one which will be synced with the backup points. The subsequent
backup levels (e.g., daily, weekly, etc) simply rotate, with
each higher backup level pulling from the one below it for its
.0 directory.
Example:
retain hourly 6
retain daily 7
retain weekly 4
daily.0/ will be copied from hourly.5/, and weekly.0/ will be
copied from daily.6/
hourly.0/ will be rsynced directly from the filesystem.
link_dest 1
If your version of rsync supports --link-dest (2.5.7 or newer),
you can enable this to let rsync handle some things that GNU cp
or the built-in subroutines would otherwise do. Enabling this
makes rsnapshot take a slightly more complicated code branch,
but it’s the best way to support special files on non-Linux
systems.
sync_first 1
sync_first changes the behaviour of rsnapshot. When this is
enabled, all calls to rsnapshot with various backup levels
simply rotate files. All backups are handled by calling
rsnapshot with the "sync" argument. The synced files are stored
in a ".sync" directory under the snapshot_root.
This allows better recovery in the event that rsnapshot is
interrupted in the middle of a sync operation, since the sync
step and rotation steps are separated. This also means that you
can easily run "rsnapshot sync" on the command line without
fear of forcing all the other directories to rotate up. This
benefit comes at the cost of one more snapshot worth of disk
space. The default is 0 (off).
verbose 2
The amount of information to print out when the program is run.
Allowed values are 1 through 5. The default is 2.
1 Quiet Show fatal errors only
2 Default Show warnings and errors
3 Verbose Show equivalent shell commands being executed
4 Extra Verbose Same as verbose, but with more detail
5 Debug All kinds of information
loglevel 3
This number means the same thing as verbose above, but it
determines how much data is written to the logfile, if one is
being written.
The only thing missing from this at the higher levels is the
direct output from rsync. We hope to add support for this in a
future release.
logfile /var/log/rsnapshot
Full filesystem path to the rsnapshot log file. If this is
defined, a log file will be written, with the amount of data
being controlled by loglevel. If this is commented out, no log
file will be written.
include [file-name-pattern]
This gets passed directly to rsync using the --include
directive. This parameter can be specified as many times as
needed, with one pattern defined per line. See the rsync(1) man
page for the syntax.
exclude [file-name-pattern]
This gets passed directly to rsync using the --exclude
directive. This parameter can be specified as many times as
needed, with one pattern defined per line. See the rsync(1) man
page for the syntax.
include_file /path/to/include/file
This gets passed directly to rsync using the --include-from
directive. See the rsync(1) man page for the syntax.
exclude_file /path/to/exclude/file
This gets passed directly to rsync using the --exclude-from
directive. See the rsync(1) man page for the syntax.
rsync_short_args -a
List of short arguments to pass to rsync. If not specified,
"-a" is the default. Please note that these must be all next to
each other. For example, "-az" is valid, while "-a -z" is not.
"-a" is rsync’s "archive mode" which tells it to copy as much
of the filesystem metadata as it can for each file. This
specifically does *not* include information about hard links,
as that would greatly increase rsync’s memory usage and slow it
down. If you need to preserve hard links in your backups, then
add "H" to this.
rsync_long_args --delete --numeric-ids --relative
--delete-excluded
List of long arguments to pass to rsync. Beginning with
rsnapshot 1.2.0, this default has changed. In previous
versions, the default values were
--delete --numeric-ids
Starting with version 1.2.0, the default values are
--delete --numeric-ids --relative --delete-excluded
This directly affects how the destination paths in your backup
points are constructed. Depending on what behaviour you want,
you can explicitly set the values to make the program behave
like the old version or the current version. The newer settings
are recommended if you’re just starting. If you are upgrading,
read the upgrade guide in the INSTALL file in the source
distribution for more information.
Quotes are permitted in rsync_long_args, eg --rsync-path="sudo
/usr/bin/rsync". You may use either single (’) or double (")
quotes, but nested quotes (including mixed nested quotes) are
not permitted. Similar quoting is also allowed in per-backup-
point rsync_long_args.
ssh_args -p 22
Arguments to be passed to ssh. If not specified, the default is
none.
du_args -csh
Arguments to be passed to du. If not specified, the default is
-csh. GNU du supports -csh, BSD du supports -csk, Solaris du
doesn’t support -c at all. The GNU version is recommended,
since it offers the most features.
lockfile /var/run/rsnapshot.pid
stop_on_stale_lockfile 0
Lockfile to use when rsnapshot is run. This prevents a second
invocation from clobbering the first one. If not specified, no
lock file is used. Make sure to use a directory that is not
world writeable for security reasons. Use of a lock file is
strongly recommended.
If a lockfile exists when rsnapshot starts, it will try to read
the file and stop with an error if it can’t. If it *can* read
the file, it sees if a process exists with the PID noted in the
file. If it does, rsnapshot stops with an error message. If
there is no process with that PID, then we assume that the
lockfile is stale and ignore it *unless* stop_on_stale_lockfile
is set to 1 in which case we stop.
stop_on_stale_lockfile defaults to 0.
one_fs 1
Prevents rsync from crossing filesystem partitions. Setting
this to a value of 1 enables this feature. 0 turns it off. This
parameter is optional. The default is 0 (off).
use_lazy_deletes 1
Changes default behavior of rsnapshot and does not initially
remove the oldest snapshot. Instead it moves that directory to
_delete.[processid] and continues as normal. Once the backup
has been completed, the lockfile will be removed before
rsnapshot starts deleting the directory.
Enabling this means that snapshots get taken sooner (since the
delete doesn’t come first), and any other rsnapshot processes
are allowed to start while the final delete is happening. This
benefit comes at the cost of using more disk space. The default
is 0 (off).
The details of how this works have changed in rsnapshot version
1.3.1. Originally you could only ever have one .delete
directory per backup level. Now you can have many, so if your
next (eg) hourly backup kicks off while the previous one is
still doing a lazy delete you may temporarily have extra
_delete directories hanging around.
linux_lvm_snapshotsize 2G
LVM snapshot(s) size (lvcreate --size option).
linux_lvm_snapshotname rsnapshot
Name to be used when creating the LVM logical volume
snapshot(s) (lvcreate --name option).
linux_lvm_vgpath /dev
Path to the LVM Volume Groups.
linux_lvm_mountpath /mnt/lvm-snapshot
Mount point to use to temporarily mount the snapshot(s).
UPGRADE NOTICE:
If you have used an older version of rsnapshot, you might
notice that the destination paths on the backup points have
changed. Please read the INSTALL file in the source
distribution for upgrade options.
backup /etc/ localhost/
backup root@example.com:/etc/ example.com/
backup rsync://example.com/path2/ example.com/
backup /var/ localhost/ one_fs=1
backup lvm://vg0/home/path2/ lvm-vg0/
backup_script /usr/local/bin/backup_pgsql.sh pgsql_backup/
Examples:
backup /etc/ localhost/
Backs up /etc/ to <snapshot_root>/<retain>.0/localhost/etc/
using rsync on the local filesystem
backup /usr/local/ localhost/
Backs up /usr/local/ to
<snapshot_root>/<retain>.0/localhost/usr/local/ using rsync
on the local filesystem
backup root@example.com:/etc/ example.com/
Backs up root@example.com:/etc/ to
<snapshot_root>/<retain>.0/example.com/etc/ using rsync
over ssh
backup root@example.com:/usr/local/ example.com/
Backs up root@example.com:/usr/local/ to
<snapshot_root>/<retain>.0/example.com/usr/local/ using
rsync over ssh
backup rsync://example.com/pub/ example.com/pub/
Backs up rsync://example.com/pub/ to
<snapshot_root>/<retain>.0/example.com/pub/ using an
anonymous rsync server. Please note that unlike backing up
local paths and using rsync over ssh, rsync servers have
"modules", which are top level directories that are
exported. Therefore, the module should also be specified in
the destination path, as shown in the example above (the
pub/ directory at the end).
backup /var/ localhost/ one_fs=1
This is the same as the other examples, but notice the
fourth column. This is how you specify per-backup-point
options to over-ride global settings. This extra parameter
can take several options, separated by commas.
It is most useful when specifying per-backup rsync excludes
thus:
backup root@somehost:/ somehost
+rsync_long_args=--exclude=/var/spool/
Note the + sign. That tells rsnapshot to add to the list
of arguments to pass to rsync instead of replacing the
list.
backup lvm://vg0/home/path2/ lvm-vg0/
Backs up the LVM logical volume called home, of volume
group vg0, to <snapshot_root>/<interval>.0/lvm-vg0/. Will
create, mount, backup, unmount and remove an LVM snapshot
for each lvm:// entry.
backup_script /usr/local/bin/backup_database.sh
db_backup/
In this example, we specify a script or program to run.
This script should simply create files and/or directories
in its current working directory. rsnapshot will then take
that output and move it into the directory specified in the
third column.
Please note that whatever is in the destination directory
will be completely deleted and recreated. For this reason,
rsnapshot prevents you from specifying a destination
directory for a backup_script that will clobber other
backups.
So in this example, say the backup_database.sh script
simply runs a command like:
#!/bin/sh
mysqldump -uusername mydatabase > mydatabase.sql
chmod u=r,go= mydatabase.sql # r-------- (0400)
rsnapshot will take the generated "mydatabase.sql" file and
move it into the <snapshot_root>/<retain>.0/db_backup/
directory. On subsequent runs, rsnapshot checks the
differences between the files created against the previous
files. If the backup script generates the same output on
the next run, the files will be hard linked against the
previous ones, and no additional disk space will be taken
up.
Remember that tabs must separate all elements, and that there must
be a trailing slash on the end of every directory.
A hash mark (#) on the beginning of a line is treated as a comment.
Putting it all together (an example file):

USAGE
rsnapshot can be used by any user, but for system-wide backups you will
probably want to run it as root.
Since backups usually get neglected if human intervention is required,
the preferred way is to run it from cron.
When you are first setting up your backups, you will probably also want
to run it from the command line once or twice to get a feel for what
it’s doing.
Here is an example crontab entry, assuming that backup levels hourly,
daily, weekly and monthly have been defined in /etc/rsnapshot.conf
0 */4 * * * /usr/local/bin/rsnapshot hourly
50 23 * * * /usr/local/bin/rsnapshot daily
40 23 * * 6 /usr/local/bin/rsnapshot weekly
30 23 1 * * /usr/local/bin/rsnapshot monthly
This example will do the following:
6 hourly backups a day (once every 4 hours, at 0,4,8,12,16,20)
1 daily backup every day, at 11:50PM
1 weekly backup every week, at 11:40PM, on Saturdays (6th day of
week)
1 monthly backup every month, at 11:30PM on the 1st day of the
month
It is usually a good idea to schedule the larger backup levels to run a
bit before the lower ones. For example, in the crontab above, notice
that "daily" runs 10 minutes before "hourly". The main reason for this
is that the daily rotate will pull out the oldest hourly and make that
the youngest daily (which means that the next hourly rotate will not
need to delete the oldest hourly), which is more efficient. A
secondary reason is that it is harder to predict how long the lowest
backup level will take, since it needs to actually do an rsync of the
source as well as the rotate that all backups do.
If rsnapshot takes longer than 10 minutes to do the "daily" rotate
(which usually includes deleting the oldest daily snapshot), then you
should increase the time between the backup levels. Otherwise
(assuming you have set the lockfile parameter, as is recommended) your
hourly snapshot will fail sometimes because the daily still has the
lock.
Remember that these are just the times that the program runs. To set
the number of backups stored, set the retain numbers in
/etc/rsnapshot.conf
To check the disk space used by rsnapshot, you can call it with the
"du" argument.
For example:
rsnapshot du
This will show you exactly how much disk space is taken up in the
snapshot root. This feature requires the UNIX du command to be
installed on your system, for it to support the "-csh" command line
arguments, and to be in your path. You can also override your path
settings and the flags passed to du using the cmd_du and du_args
parameters.
It is also possible to pass a relative file path as a second argument,
to get a report on a particular file or subdirectory.
rsnapshot du localhost/home/
The GNU version of "du" is preferred. The BSD version works well also,
but does not support the -h flag (use -k instead, to see the totals in
kilobytes). Other versions of "du", such as Solaris, may not work at
all.
To check the differences between two directories, call rsnapshot with
the "diff" argument, followed by two backup levels or directory paths.
For example:
rsnapshot diff daily.0 daily.1
rsnapshot diff daily.0/localhost/etc daily.1/localhost/etc
rsnapshot diff /.snapshots/daily.0 /.snapshots/daily.1
This will call the rsnapshot-diff program, which will scan both
directories looking for differences (based on hard links).
rsnapshot sync
When sync_first is enabled, rsnapshot must first be called with the
sync argument, followed by the other usual cron entries. The sync
should happen as the lowest, most frequent backup level, and right
before. For example:
0 */4 * * * /usr/local/bin/rsnapshot sync &&
/usr/local/bin/rsnapshot hourly
50 23 * * * /usr/local/bin/rsnapshot daily
40 23 1,8,15,22 * * /usr/local/bin/rsnapshot weekly
30 23 1 * * /usr/local/bin/rsnapshot monthly
The sync operation simply runs rsync and all backup scripts. In
this scenario, all calls simply rotate directories, even the lowest
backup level.
rsnapshot sync [dest]
When sync_first is enabled, all sync behaviour happens during an
additional sync step (see above). When using the sync argument, it
is also possible to specify a backup point destination as an
optional parameter. If this is done, only backup points sharing
that destination path will be synced.
For example, let’s say that example.com is a destination path
shared by one or more of your backup points.
rsnapshot sync example.com
This command will only sync the files that normally get backed up
into example.com. It will NOT get any other backup points with
slightly different values (like example.com/etc/, for example). In
order to sync example.com/etc, you would need to run rsnapshot
again, using example.com/etc as the optional parameter.
EXIT VALUES
0 All operations completed successfully
1 A fatal error occurred
2 Some warnings occurred, but the backup still finished
FILES
/etc/rsnapshot.conf

du(1), crontab(1)
DIAGNOSTICS
Use the -t flag to see what commands would have been executed. This
will show you the commands rsnapshot would try to run. There are a few
minor differences (for example, not showing an attempt to remove the
lockfile because it wasn’t really created in the test), but should give
you a very good idea what will happen.
Using the -v, -V, and -D flags will print increasingly more information
to STDOUT.
Make sure you don’t have spaces in the config file that you think are
actually tabs.
Much other weird behavior can probably be attributed to plain old file
system permissions and ssh authentication issues.
BUGS
Please report bugs (and other comments) to the rsnapshot-discuss
mailing list:
http://lists.sourceforge.net/lists/listinfo/rsnapshot-discuss
NOTES
Make sure your /etc/rsnapshot.conf file has all elements separated by
tabs. See /usr/share/doc/rsnapshot/examples/rsnapshot.conf.default.gz
for a working example file.
Make sure you put a trailing slash on the end of all directory
references. If you don’t, you may have extra directories created in
your snapshots. For more information on how the trailing slash is
handled, see the rsync(1) manpage.
Make sure to make the snapshot directory chmod 700 and owned by root
(assuming backups are made by the root user). If the snapshot directory
is readable by other users, they will be able to modify the snapshots
containing their files, thus destroying the integrity of the snapshots.
If you would like regular users to be able to restore their own
backups, there are a number of ways this can be accomplished. One such
scenario would be:
Set snapshot_root to /.private/.snapshots in /etc/rsnapshot.conf
Set the file permissions on these directories as follows:
drwx------ /.private
drwxr-xr-x /.private/.snapshots
Export the /.private/.snapshots directory over read-only NFS, a read-
only Samba share, etc.
See the rsnapshot HOWTO for more information on making backups
accessible to non-privileged users.
For ssh to work unattended through cron, you will probably want to use
public key logins. Create an ssh key with no passphrase for root, and
install the public key on each machine you want to backup. If you are
backing up system files from remote machines, this probably means
unattended root logins. Another possibility is to create a second user
on the machine just for backups. Give the user a different name such as
"rsnapshot", but keep the UID and GID set to 0, to give root
privileges. However, make logins more restrictive, either through ssh
configuration, or using an alternate shell.
BE CAREFUL! If the private key is obtained by an attacker, they will
have free run of all the systems involved. If you are unclear on how to
do this, see ssh(1), sshd(1), and ssh-keygen(1).
Backup scripts are run as the same user that rsnapshot is running as.
Typically this is root. Make sure that all of your backup scripts are
only writable by root, and that they don’t call any other programs that
aren’t owned by root. If you fail to do this, anyone who can write to
the backup script or any program it calls can fully take over the
machine. Of course, this is not a situation unique to rsnapshot.
By default, rsync transfers are done using the --numeric-ids option.
This means that user names and group names are ignored during
transfers, but the UID/GID information is kept intact. The assumption
is that the backups will be restored in the same environment they came
from. Without this option, restoring backups for multiple heterogeneous
servers would be unmanageable. If you are archiving snapshots with GNU
tar, you may want to use the --numeric-owner parameter. Also, keep a
copy of the archived system’s /etc/passwd and /etc/group files handy
for the UID/GID to name mapping.
If you remove backup points in the config file, the previously archived
files under those points will permanently stay in the snapshots
directory unless you remove the files yourself. If you want to conserve
disk space, you will need to go into the <snapshot_root> directory and
manually remove the files from the smallest backup level’s ".0"
directory.
For example, if you were previously backing up /home/ with a
destination of localhost/, and hourly is your smallest backup level,
you would need to do the following to reclaim that disk space:
rm -rf <snapshot_root>/hourly.0/localhost/home/
Please note that the other snapshots previously made of /home/ will
still be using that disk space, but since the files are flushed out of
hourly.0/, they will no longer be copied to the subsequent directories,
and will thus be removed in due time as the rotations happen.
