I'm also curious about the additional overhead (in disk space) that is
created by frequent rdiff-backup runs. If one backs up daily, how much
more disk space is used than if one backs up weekly? In theory no more
because 7 x daily incremental diffs have the same info as 1 x weekly
incremental diff.
I was running a backup of about 150 GB of data three (home directories)
about 3 times a day, and it was taking 8 MB per incremental backup with
rdiff-backup 1.0.5, even if nothing had changed. It may well be less with
more recent versions, due to (1) compressed metadata and (2) incremental
patches to metadata.
Cheers, Chris.
Hi Chris
Thanks for your input that is interesting and makes me think that very
frequent backups could be too much of a good thing, though 8MB is not
a lot and in your case the difference in disk space over a year
compared with daily backups would come to c.4GB.
Regarding my other question about locked in-use files, my researches
so far suggest that
