Backing up sub volume to another drive
2 projects | /r/btrfs | 1 Apr 2022

I'm planning to set up https://github.com/nachoparker/btrfs-sync along with its snapshot companion script. As I've not tried it yet I can't specifically recommend it, but it seems to offer the main backup benefits you get with the popular zfs backup scripts.

I accidentally programmed my server to back up all files... even backups
1 project | /r/programminghorror | 20 May 2023

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).

Fast and comprehensive system backup. Can Linux software do it?

the smoothest backup tool i have seen for Linux is btrbk works real nice and is customizable for almost all use-cases BTRFS rocks :)
Trying to understand the real impact of not having ECC
1 project | /r/DataHoarder | 6 Feb 2023

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.
BTRFS snapshots and btrbk as a backup solution
1 project | /r/btrfs | 1 Feb 2023

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.
btrbk: subvolume has no UUID error

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
incremental snapshot backup tool: which one should i go for?

btrbk is the best solution I know.
how do you Backup your system?
5 projects | /r/EndeavourOS | 23 Nov 2022

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:
