Thanks Robert and to everyone for your feedback. Really appreciate it ! On Apr 28, 2020, at 1:45 PM, Robert Trevellyan <robert.trevell...@gmail.com<mailto:robert.trevell...@gmail.com>> wrote:
I've been using ZFS for storage on Ubuntu Server for several years now. Among other things, the server runs two BackupPC 4 instances in LXC containers. One backs up local machines, the other backs up cloud servers. I haven't run into any serious problems. My use case is on a much smaller scale than yours in terms of storage and number of hosts, but the backups in both BPC instances include large numbers of small files. IMO the fact that ZFS has no limit on inodes is one of the attributes that makes is a good choice, aside from the obvious (reliability and scale).

Most of the files we'll be backing up are fairly small (under a few mb). We've got a handful of large databases the we'll also be backing up dumps of. Thanks !

We’ve been running backuppc for a few years and now have new server for it with 100 TB of space in hardware raid 6 array. We’re wondering what the recommended filesystem for backuppc would be on an array of this size ? Our priority is stability over performance. We’ll be running ubuntu as the operating system. Most of the hosts we’re backing up are fairly small (under 1 TB) linux servers. Right now we’re backing up about 100 servers for a total of around 20 TB. (We’re expecting the new server to last a few years).
