Re: deduplicating file systems: VDO with Debian?
I am no expert (in Linux, backporting or anything else) and cannot emit
a viable advice about what your backup plan should be. You are in better
position to evaluate your needs, your means and design a satisfying
backup plan accordingly.
What I was underlyning is that in my opinion you are confusing
deduplicating during backup and incremental/differential backups.
(Perhaps in your context that has no consequences and is thus unimportant).
To *me* what you are talking about is incremental/differential backups,
not deduplicating backups.
For example, I am myself using Deja-Dup (based upon Duplicity, itself
based upon librsync) for my basic home laptop backup: it's incremental
backups but I would not call it deduplicating backups.
The Wikipedia deduplicating paragrah of their backup article has an
example of 100 identical workstations having a backup storage need
divided by 100 by deduplication.
