Question -
We use rdiff (not rdiff-backup) to do our incremental file backups.
We do:
1. Copy the file to a staging area (so the file won't disappear or be
modified while we work on it)
2. Hash the original file, and computes an rdiff signature (used for
delta differencing)
3.
I used rdiff.exe briefly before moving to rdiff-backup. Certainly
rdiff-backup does your 2-4 'under the hood' and fast. It is highly
optimised both for speed of transfer and for storage space - but does
require a reliable connection between source and destination. It does
not do your 1, you
Are you sure the rdiff delta's are encrypted?
I know the primary backup is not.
We address this by placing our rdiff backups on encrypted filessystems
(using encfs).
So our process is:
1) Create a LVM snapshot
2) run rdiff-backup sending data to a local encrypted filesystem.
3) use rsync to
