       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
       included below.

       -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.

       -s --simple
           This option forces filesystem to use simple list as a data
           structure and as a result program require a little less memory.

       -t --tree
           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.

       -l --last
           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.

       -v --version
           Displays version of archfs.
