I use rdiff-backup it uses the rsync alorythm but it keeps the
increments so you can recover deleted files or the old form of file. I
makes weekly backups and delete files in the backup files which are
older than 3 months.
Take care with --remove-older-than option, as the man page says:
"Note that snapshots of deleted files are covered by this operation.
Thus if you deleted a file two weeks ago, backed up immediately after‐
wards, and then ran rdiff-backup with --remove-older-than 10D today, no
trace of that file would remain."
You can loose valuable old files. So, one thing I really miss in
rdiff-backup is an option to remove backups older than <a point in time>
AND newer than <another point in time>. Thus, I could reduce daily
backups to weekly, etc. But still, I can loose files.
In a near future, I think I'll switch to venti(1) and/or vbackup(8) of
"Plan 9 port":
http://swtch.com/plan9port/
Venti is "Write Once Read Many" archival storage server used to store
files hierarchy for example. On the other hand, Vbackup is used to
store efficiently entire logical volumes from *nix to a Venti server.
But this involves to know a little about Plan 9 concepts, etc.
