archfs - filesystem for rdiff-backup repositories
archfs mountpoint repository..
archfs -r repository.. -m mountpoint
archfs is a filesystem that allows to browse through the rdiff-backup
repositories. It is created in user space and besides the requirement
of FUSE kernel module it can be set without the need of root
privileges. It may present data in different layouts - as a default it
simply presents all revisions with contents at the time when certain
backup had been made.
Files stored in the rdiff-backup archive can be presented in one of two
layouts. As a default filesystem displays all increments with precise
image of a stored directory. If -l option is used, however, then files
from the last increment will be displayed as directories, each holding
all versions of this file.
This programs follows the usual GNU command line syntax, with long
options starting with two dashes (‘-´). A summary of options is
-m --mount path
Specify path mount point.
-r --repositories repository..
Specify paths to repositories. If you use this option you have to
specify mount point by option.
This option forces filesystem to use simple list as a data
structure and as a result program require a little less memory.
This option explicitly forces filesystem to use directory tree as a
data structure. This makes all operations faster, but requires a
bit more memory. This data structure is chosen as a default.
-c --caching limit
Through this option user can use file caching, which increases
efficiency on multiple accesses to one file. Without this function
limit is set to 0 and there is no caching (this uses in fact
simpler, better tested code). Limit does not define how many cached
files can be stored on disk; instead it defines how many files can
be cached if there are no open files. If there are open files, then
the limit is decreased by their number. In certain cases, when
multiple files are open at the same time, no caching will be done,
so the disk usage can stay as low, as user wants.
-d --directory path
As a default archfs creates temporary directory to store cache and
other files in /tmp. Using this option, we can define some other
directory, where temporary files directory is created.
This option changes way of presenting files in the filesystem. When
invoked files from the most recent increment will be presented as
directories, each holding every version certain file.
