Activated btrfs snapshot capability too late. How to take advantage of it now?


#1

Well, I set up a server on a btrfs subvolume and didn’t activate it writing the backupfolder file under /etc/urbackup.

Now, I’ve activated it after some machines already created their backups… do I have to do anything to take advantage of btrfs snapshotting now that the backups have been already created?

What’s the best course of action? Do I have to start over?

I think you just change the format in which you save the backups.
From vhd/vhdz to raw cow file.

That option was missing till you passed urbackup_snapshot_helper test

I guess it will do the next backup full backup.


#3

He s speaking about the fast that urbackup can now store file backups as a set of btrfs snapshots, instead of linking between different backup versions.


#4

It did finally just start using the feature for the next backups. Didn’t have to do anything.


#5

Where do you see that its using the feature?

Logged into the server via ssh, listed the btrfs subvolumes and saw multiple subvolumes :slight_smile:
