[BackupPC-users] Migrate Pool from non-compression to compression?

[Christian V. <cvo...@kn...>]

Hi,

I have a V4 pool where I had compression disabled for couple of months. 
Now I decided (after thinking twice ;)) to enable compression on the pool.

Is there any chance to move the existing (non compressed) pool into the 
cpool?

Or best to just wait another months until the pool-files are getting 
outdated?

[Note:
I used BTRFS with compression inside a VM. I prefer enabling it on 
filesystem level so I disabled compression for BackuppPC initially. But 
as this is a VM running on QNAP NAS with underlying ZFS it doe not make 
sense to have a CoW fs like BTRFS on top of anothe CoW fs (QNAP ZFS). So 
I decided to move the pool to ext4 instead of btrfs. But as the VM is 
using luks encryption I can not enable ZFS compression as it will not 
see any compression possibilities. So I want to enable it on BackupPC 
and possibly moving existing uncompressed pool files to compressed pool.

So any ideas?

Thanks!

Christian
