Using Timeshift with raid

[tony-at]

I'm having problems when trying to select my software raid partition as a snapshot location for timeshift. It just doesn't appear in the gui. Is it possible to set an ext4 partition on a mdadm raid as a snapshot location?

Hello, same here with a ZFS raidz1. The drives appear in destination selection (available linux filesystems), but selecting one (which actually doesn't make sense), it says: "No linux filesystem". Greetings

This is probably not a bug, rather a feature request, anyway +1. Also an ext4 on dmraid shouldn't be a big issue to support. I guess there might be concerns about the availability of zfs/dm/md volumes when you need to perform a recovery... that's maybe why they are excluded.

raid 5 here, +1

[brendan-pike]

raid 1 here, +1

[achmonth]

I need this as well, +1

[ren-kun]

Same on my end. +1

[sduensin]

Yep. +1

I have this issue as well. Over 1TB free on my RAID, but no space available in Timeshift for snapshots. The individual drives that make up the RAID are showing but inaccessible, and the RAID volume is not detected. Thanks.

+1 for raid 1

+1 for mdadm raid 10 as well

I have a 8TB ext4 RAID-10 and I would LOVE if my NVMe could get daily backups to the RAID. The reason is that I'm on Ryzen and also do some other unstable work. Daily backups to the RAID without a custom RSYNC script (as I use now) would be amazing.

Up! :)

Intel Onboard Raid1 here. Availability on recovery shouldn't be a big issue I guess? +1

just use sudo timeshift --list-devices to list availables devices (including raid partitions) and then sudo timeshift --snapshot-device /dev/mdXXX with correct device name to set your backup destination

The interface still doesn't list the partition but the backup seems ok

thanks @Jpjob314! backup is one thing have you tried to restore in raid as well?

PS +1 for raid

[fourstepper]

+1 for RAID, @Jpjob314 did you successfully restore using the method above?

[pinsonnj]

Nope ! Never had to ^^

[fourstepper]

Unfortunate... Now we will never know if it actually works! :D

Thank you though!

[Wikinaut]

Works.

Is there a plan, when this issue will become fixed?

Does it work with BTRFS RAID? When I list-devices it lists the partition that are in use by the btrfs raid volume, but not the btrfs raid volume itself.

I'd really appreciate a solution to this as well. Want to be able to backup my back my 1TB system hard disc onto my 8TB RAID1 discs (which store the /home directory). Can't see the raid partition on the "Select Snapshot Location" page.

If someone is interested in adding RAID support please go ahead and submit a PR

+1 I would love to see it being shown in the ui, but still works fine after setting the raid as destination per command Raid 1 3 Partitions

Does this still work for you? I'm using Ubuntu 21.10 with a software raid 5 array (/dev/md0).

sudo timeshift --list-devices

For me on newest Mint (una) it works with a raid 1 without problems

I was able to fix my problem by modifying one line. Can anyone try this fix?
