you can use for example FreeNAS (ZFS based) which can sync snapshots.

Re: [BackupPC-users] Backing up the BackupPC pool
Hannes- Option 2, Copying the the pool (tar, then copy) to a remote server appears to be viable for small installations, and we've tested that with success. But at a certain point, if you have a lot of machines, and your pool gets large, that process becomes un-manageable. (Our pool is about 3.5TiB for just over 100 hosts backed up). Just tar-ing the data store up takes most of the day. So, Option 1 starts to look more appealing. It may be that your primary instance (local) has a more aggressive retention schedule than the remote copy, or other differences like how frequently backups run. -- Ray Frush On Wed, Aug 9, 2017 at 2:47 PM, Hannes Elvemyrwrote: > Hi! > > I'm using BackupPC for all my machines and it's great!

This would be ZE wise (and first) thing to do; think about little inconveniences that will happen one day or another to your work building: fire, lightning strike, flooding, gas (or bomb) explosion, dragon attack, rabid customer, and worse of all: a mad Craig Barratt attack (well, he's already mad, so it's not a matter of "if" but really a matter of "when";-p) It will also give you the main benefit of rsync by tunneling only what's necessary (only your first backup will take more time.) Think about the whole pool size and the time needed to tunnel it elsewhere… Jean-Yves -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
[BackupPC-users] Backing up the BackupPC pool
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?
