I do an `rsync` of the latest monthlies (once a month) to a rotating set of drives to cover the 'datacenter burned down' scenario. Since snapshots are not backups I use `btrfs send/receive` to replicate the daily snapshots to a different btrfs filesystem on spinning rust, w/ the same retention policy. I do incremental sends, so I can never remove the most recent snapshot.)

Since I use entirely SSD storage I also have a script that mails me a usage report on those snapshots, and I manually prune ones that accidentally captured something huge. the first snapshot of every year for 5 years the first snapshot of every month for 2 years the first snapshot of every week for 4 weeks `btrbk` manages the retention policy, which is roughly something like:

I use `btrbk` as a systemd service to snapshot my `/home` subvolume hourly & any other important subvolumes daily. However if you would like some ideas that are rather more realistic for a generic home user that will cover all bases for a reasonable outlay in time, effort and a few quid (but not much) then I am all ears. If your question was simply to find out what people use then that's me done. I off site via VPN links to another location. I use Veeam for back in time restores of centrally held managed file stores. I use waste/recycle bins for quick 'restores'. I use replication via NextCloud to make my data highly available. So to answer your question, I use a lot of different technologies and strategies. I have access to rather a lot more stuff as well and that is only part of my data availability plan but the point remains: I've considered the whole thing. NC/Owncloud also have a salvage bin thing and the server VM I have is also backed up and off sited (to my office) with 35 days online restore points and a GFS scheme - all with Veeam. I have put all her files into our family Nextcloud instance that I run at home. eg for wifey, I used the recycle bin (KDE in this case) and bit my tongue when told I must have done it. Now look at appropriate technologies and strategies. You get the idea - there is rather more to backups than simply 'backups'. * Your partner deletes their entire accounts (my wife did this tonight - 5 sec outage) * You drop your laptop - can you use another device to function * You delete a file four months ago - can. * You delete a file - can you recover it - how long Then decide what is an acceptable outage or loss for each scenario. Scribble a few scenarios down and think about 'what would happen if. I have access to rather a lot of gear but the same approach will work for anyone willing to sit down and have a think and perhaps spend a few quid or at least think laterally.įor starters you need to consider what could happen to your systems and your data. Given I worry about this sort of thing for a living and am a partner in the firm: I think in terms of backup, DR, BC, availability and more.
