btrbk VS TimeShift

That's still easier using snapshots and something like btrbk. Snapshot the directory at start, prune if there are too many snapshots (or snapshots get too old).

I'm on Arch, but you might still find it useful: Btrfs snapshots Arch Wiki - Incremental backup to external drive GitHub - btrbk

the smoothest backup tool i have seen for Linux is btrbk works real nice and is customizable for almost all use-cases BTRFS rocks :)

I recommend redundancy and regular verification is you want to insure your data against corruption. If you do that, you can forget about things like ECC. My setup is a NUC server running Ubuntu with a USB3-connected storage drive running BTRFS. I use btrbk to auto-snapshot and auto-replicate via incremental sends to my BTRFS backup drive, and RotKraken to track integrity of the data with a monthly verification run so that I notice corruption in time to correct it.

In pondering my backup strategy, I was wondering if I could use BTRFS snapshots and a backup tool like btrbk, which is a nice integrated snapshot/backup solution I've used happily on desktop Linux. BTRFS needs subvolumes for snapshots, so I couldn't backup the host itself (which wasn't installed with a / subvolume like other distributions I've used), but it could snapshot the VMs and containers, which have their own individual subvolumes. Then btrbk can send that snapshot in an incremental fashion to external storage.

I then installed btrbk and tried to follow the instructions to create snapshots of root and home on the SSD and then send/receive those to the HDD. I mainly used https://github.com/digint/btrbk and https://mutschler.dev/linux/fedora-btrfs-35/, but I don't use luks.

For anyone using btrfs on their system, I heartily recommend btrbk, which has served me very well for making incremental backups with a customizable retention period: https://github.com/digint/btrbk

btrbk is the best solution I know.

I use BTRBK to make and copy the BTRFS snapshots to my HDD. I schedule it to run every 3 hours using a Sytemd unit file through my own script to avoid running the backup at inconvenient moments:

The previous developer of timeshift—Tony George (GitHub) — has been the developer since 2017 (based on GitHub version history), and has recently handed off development to the Linux Mint team.

I use both timeshift & duplicity

Don't believe me or u/acejavelin69 - read what the developer has to say about user data and why it is disabled by default. https://github.com/teejee2008/timeshift

Version v22.06.6 Latest

The original dev used ubuntu and only wanted to support the default ubuntu layout: https://github.com/teejee2008/timeshift/issues/821

What system backup software can you recommend? In the past on Ubuntu I tested Timeshift, and it looks really cool. But the "main problem" is thing, that some options not work in Fedora: https://github.com/teejee2008/timeshift, specifically BTRFS. What does it mean, this is a problem?

- [Timeshift](https://github.com/teejee2008/timeshift) or [Deja Dup](https://wiki.gnome.org/Apps/DejaDup) and back-up everything.

What I tried is to add "exclude" : [ "+ /home/user1/**", "+ /root/**", "+ /home/user2/**", ], to /etc/timeshift.json as per this post but the files within those folders still aren't included in the backup.

Releases · teejee2008/timeshift Was fixed. Get PPA from that repo to have the latest release.

Are you sure you need a full on virtual machine, rather than a system snapshotting tool like Snapper or Timeshift?
