NAME
jets3t-synchronize - synchronize local directories with an Amazon S3
account
SYNOPSIS
Synchronize the contents of a local directory with S3:
jets3t-synchronize [options] UP <S3path> <path1> [[path2] .. [pathN]]
Synchronize the contents of S3 with a local directory:
jets3t-synchronize [options] DOWN <S3path> <download_dir>
OVERVIEW
jets3t-synchronize is a console (text mode) Java application for
synchronizing directories on a computer with an Amazon S3 account.
OPTIONS
-h, --help
Displays a brief summary with all options.
-n, --noaction
No action taken. No files will be changed locally or on S3, instead a
report will be generating showing what will happen if the command is
run without the -n option.
-q, --quiet
Runs quietly, without reporting on each action performed or
displaying progress messages. The summary is still displayed.
-p, --noprogress
Runs somewhat quietly, without displaying progress messages. The
action report and overall summary are still displayed.
-f, --force
Force tool to perform synchronization even when files are up-to-date.
This may be useful if you need to update metadata or timestamps in
S3.
-k, --keepfiles
Keep outdated files on destination instead of reverting/removing
them. This option cannot be used with --nodelete.
-d, --nodelete
Keep files on destination that have been removed from the source.
This option is similar to --keepfiles except that files may be
reverted. This option cannot be used with --keepfiles.
-m, --move
Move items rather than merely copying them. Files on the local
computer will be deleted after they have been uploaded to S3, or
objects will be deleted from S3 after they have been downloaded. Be
*very* careful with this option. This option cannot be used with
--keepfiles.
-b, --batch
Download or upload files in batches, rather than all at once.
Enabling this option will reduce the memory required to synchronize
large buckets, and will ensure file transfers commence as soon as
possible. When this option is enabled, the progress status lines
refer only to the progress of a single batch.
-s, --skipmetadata
Skip the retrieval of object metadata information from S3. This will
make the synch process much faster for large buckets, but it will
leave jets3t-synchronize with less information to make decisions. If
this option is enabled, empty files or directories will not be
synchronized reliably. This option cannot be used with the --gzip or
--crypto options.
-g, --gzip
Compress (GZip) files when backing up and decompress gzipped files
when restoring.
-c, --crypto
Encrypt files when backing up and decrypt encrypted files when
restoring. If this option is specified the properties must contain a
password.
--properties filename
Load the synchronizer app properties from the given file rather than
from a synchronizer.properties file in the classpath.
--credentials filename
Load your AWS credentials from an encrypted file, rather than from
the synchronizer.properties file. This encrypted file can be created
using the Cockpit application, or the JetS3t API library.
--acl ACL_string
Specifies the Access Control List setting to apply. This value must
be one of: PRIVATE, PUBLIC_READ, PUBLIC_READ_WRITE. This setting will
override any acl property specified in the synchronize.properties
file
--reportlevel level
A number that specifies how much report information will be printed:
0 - no report items will be printed (the summary will still be
printed).
1 - only actions are reported
[Prefixes N, U, D, R, F, M]
2 - differences & actions are reported
[Prefixes N, U, D, R, F, M, d, r]
3 - DEFAULT: all items are reported
[Prefixes N, U, D, R, F, M, d, r, -]
NOTES
Required properties can be provided via: a file named
synchronize.properties in the classpath (or
/etc/jets3t/synchronize.properties), a file specified with the
--properties option, or by typing them in when prompted on the command
line. Required properties are:
accesskey: Your AWS Access Key (Required)
secretkey: Your AWS Secret Key (Required)
password: Encryption password (only required when using crypto)
Properties specified in this file will override those in
jets3t.properties (or in /etc/jets3t/jets3t.properties).
REPORT
Report items are printed on a single line with an action flag followed
by the relative path of the file or S3 object. The report legend
follows:
N: A new file/object will be created
U: An existing file/object has changed and will be updated
D: A file/object existing on the target does not exist on the source
and will be deleted.
d: A file/object existing on the target does not exist on the source
but because the --keepfiles or --nodelete option was set it was not
deleted.
R: An existing file/object has changed more recently on the target than
on the source. The target version will be reverted to the older source
version
r: An existing file/object has changed more recently on the target than
on the source but because the --keepfiles option was set it was not
reverted.
-: A file is identical between the local system and S3, no action is
necessary.
F: A file identical locally and in S3 was updated due to the Force
option.
M: The file/object will be moved (deleted after it has been copied
to/from S3).
