Hi!
I'm using BackupPC for all my machines and it's great! I would now like
to protect my BackupPC pool somehow (if my BackupPC server crashes, gets
stolen or burns up I don't want to loose the data). As I see it, I have
at least two options:
1. Run a second instance of BackupPC off-site
This of course creates a new second pool, but that could actually be an
advantage if one of them somehow gets corrupted.
Pros: Two independent pools.
Cons: Complicated setup. I need a VPN between my network and the
off-site machine to get this to work, which turned out to be more
complicated than I first thought (my current router does not support
static routing, so a new router would be the first step). I would also
need to sync the BackupPC configuration from my main BackupPC instance
to the second one (if I change some configuration on my main instance, I
would also like the second instance to get that change).
2. Copying the pool and send it off-site
Pros: No need for a second BackupPC instance. Seems to be the easier
solution if I can find out how to make a reliable copy of the pool.
Cons: How to copy the pool? The version 4 documentation says that “In
V4, since hardlinks are not used permanently, duplicating a V4 pool is
much easier, allowing remote copying of the pool.”. Sound great, but how
do I know that BackupPC is not reading/writing to the pool during the
copying process (maybe some backup is running or BackupPC_Nightly could
start doing some cleaning). Copying a large pool over a bad Internet
connection could take hours…
Any thought on this? How do you get redundancy of your BackupPC data?
Thanks!
