Hey fellow nerds. How do you handle large-ish volume backups between Linux hosts? About 1TB of data. Source has 100Mbps upload. Receiving end is Gbit. Incrementals will be essential, since full backup is nearly a day&#39;s worth of upload. FOSS suggestions only at this stage. It&#39;s currently performing backups put of my control with Veeam and I&#39;m a bit nervous about the whole situation being out of my hands. #linux #backups #nerdery

@lakeswimmer@aus.social rsync with compression. How much speedup you will get depends on how much data is new. The expense of restarting on error will be painful, so use partials if link reliability is an issue.

@lakeswimmer@aus.social I use #rsnapshot. Been using it for years and it works great. I'm also one of the project maintainers so am biased. In a brand new installation where everything used #ZFS (and really, everything *should* use ZFS - if it's not properly supported in your OS the OS is faulty and you should use a different one) then these days I'd use zfs send/recv, wrapped in #sanoid / #syncoid - https://github.com/jimsalterjrs/sanoid

@lakeswimmer@aus.social rsync is minimalistic, but does the job.

@lakeswimmer@aus.social I believe the classic tool here is rsync. It's pretty good.

@lakeswimmer@aus.social I have (some time ago) read good things about Borg backup. Have not yet tried it myself though.... https://www.borgbackup.org/
