Can you please share your backup strategies for linux? I’m curious to know what tools you use and why?How do you automate/schedule backups? Which files/folders you back up? What is your prefered hardware/cloud storage and how do you manage storage space?
Borg backup is gold standard, with Vorta as a very nice GUI on machines that need it. Otherwise, all my other Linux machines are running in proxmox hypervisors and have container/snapshot/vm backups regularly through proxmox backup server to another machine. All the backup data is then replicated regularly, remotely via truenas scale replication tasks.
Borg via Vorta handles the hard parts: encryption, compression, deduplication, and archiving. You can mount backup snapshots like drives, without needing to expand them. It splits archives into small chunks so you can easily upload them to your cloud service of choice.
Adding my “Me too” to Vorta/Borg. I use it with Borgbase, which I like because it’s legitimately cheap and they support Borg development. As well, you can set Borg backups with Borgbase to “append only,” which prevents ransomware or other unexpected “whoopsies” from wiping out your backup history.
I backup most of my computer every hour, but have pruning rules that make sure things don’t get too out of hand. I have a second backup that backs everything up to my NAS (using Vorta, again). This is helpful for things like my downloads folder, virtual machines, or STEAM library - things I wouldn’t want to backup over the network, but on occasion I do find myself going “whoops, I wanted that.”
I also have Vorta working on my Mom’s Macbook, then have Borgbase send me an email when there isn’t any activity for longer than a couple of days. Once I got automatic pruning working right I never had to touch this again.
