Hello everyone. Today I decided to reinstall the latest version of Garuda Gnome. Rather than manually importing my configs and settings one at a time, I've tried importing my snapper snapshot that i copied to an external drive. The problem is, after i copied it back to the /.snapshots/ directory, the backup still does not show up in garuda assistant. It also does not show up in snapper list in terminal. I've tried searching online on how to import snapper backups with no luck.

My imported backup is called "13" and it is missing below. Here is my output of snapper list:

Does anyone know a solution? It would be very much appreciated.

Well, that would be the reason.

How did you move the snapshot between drives?

a simple copy and paste solution during a bootable usb session before installing garuda. My steps:

  1. using garuda welcome, mount previous gnome system using the chroot function in garuda welcome in bootable iso
  2. Old system mounted to /mnt
  3. sudo cp -r /mnt/.snapshots/13 /run/media/external_drive_3

In new system after installation:

  1. su
  2. cp -r /run/media/external_drive_3/13 /.snapshots

That doesn't copy the snapshot. It copies the snapshot contents out of the snapshot. That is why snapper doesn't see the snapshot, it isn't a snapshot anymore.

Also, sudo cp -r probably would break all the permissions so I don't think you can use that for much.

That being said, is there a reason to reinstall and then restore a snapshot? That would remove any benefits of the reinstall even if it did work.

i see, well i guess it was my fault then :sweat_smile:

No reason, just for insurance in case i forget anything. But is there a proper way to backup snapper snapshots to an external and move them back to root for restoration?

You need a btrfs filesystem on both devices and then you can use btrfs send/receive to send the snapshot to other device. Then reverse the operation to put it back. The btrfs devices can be on the same machine or different machines connected by a network.

Thanks, ill look that up. Also can snapper directly backup to the external if i formated it to btrfs?

#10

No, but there are some 3rd party programs that take your local snapper snapshots and replicate them to an external or remote device automatically.

#11

Alright, thanks for your help. Ill try out something like snap-sync and see how it goes.

As a side note, the data you have stored in /.snapshots/13 is probably consuming a lot of disk space because it isn't a snapshot.
