Re: [BackupPC-users] I'd like to make a suggestion to the BPC devsm

Back to the original request - you could set up a second BackupPC host (using ClientNameAlias to point to the real host) to do incrementals-only (with rsync) every hour. However, as others have noted, it's a lot less efficient to do that versus snapshots: rsync has to traverse the whole client file system every hour looking for changes, while snapshot systems do copy-on-write (ie: they process only the changes as they happen).

OMFG, ZE missing link ? ;-p)

As servers structures are always identical, local daemons excepted, we
use another way to do so:
boot on a FAI server,
install a minimal system, including rsync,
restore the whole system using BPC,
reboot,
online & operational.

This stays an exceptional procedure, as all servers hardware go through a
2 weeks burn-in before being put in production - most of the breakage
coming from HDz &| SSDz.

Just in case, partitions tables are extracted and dumped on long-term
backup redundant servers and also printed to be inserted in our local
paper documentation.

The PITA of a few w$ systems will be definitely eradicated as of 2018-Q3.
