rdiff-backup question

[Monezz]

Borrowed some wisdom from the extensive rdiff-backup man page.

You have to execute the --remove-older-than command on your source
directory in addition to the backup command.
man page:  "rdiff-backup cannot remove-older-than and back up or
restore in a single session.  In order to both backup a directory and
remove old files in it, you must run rdiff-backup twice."

If you have local backups, you can also execute the command on your
backup directory.

rdiff-backup --remove-older-than 2W host.net::/remote-dir
will restult in
ssh -C host.net rdiff-backup --server --remove-older-than 2W /remote-dir
so with local backup it will probable be more effictient to omit the
server and run it on the target directory.

--remove-older-than  will remove the incremental backup information,
not the files , older then specified time.
In your case, if you delete a file, you won't be able to restore it
after 2 weeks.
