Hi list,
I'm searching a valid backup system to perform backups of 3 server, one
local and 2 remote, and 2 linux workstation. (this number could be
higher in future). Currently I'm testing bacula, scripted rsync with
hardlink and borgbackup on C8.1.
Bacula works without any problem, well tested, solid but complex to
configure. Tested on a single server (with volumes on disk) and a full
backup of 810gb (~150000 files) took 6,30 hours (too much). I would run
deduplication but 1. bacula on C8 is not compiled with aligned 2. bacula
put attention on some possibile bad scenario where deduplication could
be a problem in losing one block that could break many files with the
same shared block. So deduplication is secure or I should be away from it?
scripted rsync. Simple, through ssh protocol and private key. No agent
required on target. I use file level deduplication using hardlinks. To
perform compression and block deduplication I could use fs like zfs (not
available from epel) or use something like stratis (I don't checked if
it offer deduplication in this moment). Encryption could be performed on
fs level. Using a scripted rsync is the simpler way but there is
something that could be leaved out by me (or undiscovered error). Simple
to restore.
BorgBackup is another solution similar to rsync in some way. It works
like rsync through ssh but while rsync simply sends data, borg run
deduplication, compression and encryption on place. Why is similar
rsync? Because I need another script to run borg. It is not a complete
solution and it works on push method and not pull like with bacula or
rsync. If I would manage all my server from a central backup server is a
problem, so to accomplish this I should run the borg command from the
central server on the target server that point back to the remote
repository (located on the central server). There is another solution
with borg: using sshfs but is 4 time slower (too much solwer).
I have not so much experiences on backups and choosing the bad tool
could be dangerous so I need some suggestion.
What backup solution do you suggest for my scenario?
Thank you in advance.
Alessandro.
