Good idea to have "totally" independent backups, but do note that if they're both provided by BackupPC then the word "totally" is perhaps overstating the case somewhat. There's a risk that a failure in the backup software itself will give you the same problem on both of the "totally" independent backup systems and there's even a risk that, if both systems are running simultaneously, something malicious will get into both systems simultaneously and do damage. Result, misery. The use of e.g. a different operating system on the backup system is also worth considering, so backing up a few Windows boxes using a Linux box makes sense to me (although I'm not sure that I'd ever consider doing that the other way around - I'd consider that a Windows backup server would put any linux boxes on the same network at unnecessary risk). I too have an ("almost") independent BackupPC system on an old surplus box, but it's switched OFF most of the time, so even if a malicious act or software fault causes data loss on the main backup, the inactive one won't suffer a coincident loss. I also employ ad-hoc, parallel backups using tar and rsync, which copy things which change infrequently, and a few database dumps (that covers most stuff here) to things big SD cards (via USB sticks, which are almost inherently offline most of the time). The backup boxes also run their own (more or less independent) firewalls. Of course the independent backup boxes aren't all in the same building. PS: The wife's Pi4B has been running fine for a few weeks but then she plugged in a DVD reader. It's now crashed (judging by the language) at least five or six times in the last 24 hours. I just thought that I'd mention it, in case you use Pi4Bs for backup despite my dire warnings. PPS: Guys, for those of us on the digest list, do you think you could trim your posts a bit? Most of the time I don't read the dozen-times copied diatribes so it almost defeats the point of a mailing list. -- 73, Ged. _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/
