It's backing up 193 hosts in total, the pool is ~15TB, ~27 million files. The hosts are a mix of a lot of different stuff (mostly VM, but also a few appliances, and physical servers), with various backup frequency and history config. Most are backed up daily, but some are weekly. It usually represent between 200 and 600GB of new data per day. I'm running this on a single box with those spec : * CPU Intel Xeon D-1541 @ 2.10GHz * 32GB of RAM * 2x120GB SSD for the OS (CentOS 7) * 4x12TB SATA in a ZFS pool (~ RAID10) I'm using the lz4 compression provided by ZFS, so turned the BackupPC one off. While I do see some slowliness from time to time, it's working well. Long story short: don't bother with CPU. Except for the very first backups where it can be a bottleneck, disk I/O is what will limit general speed. Spend more in fast disks or SSD. If using ZFS, NVMe as a slog can help (or as special metadata vdev, although I haven't tested it yet). And as much RAM as you can. with what you have left, choose a decent CPU, but don't spend too much on it.
