Hi there, Apologies, I wrote this out and then forgot to send it. Late night.
FWIW I agree with with the consensus so far. :) On Sat, 7 Jun 2025, Christian V?lker wrote:
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 Or best to just wait another months until the pool-files are getting outdated? ...
Personally, I think I'd start again. Here's why: in the documentation at http://piplus.local.jubileegroup.co.uk/BackupPC_Admin?action=view&type=docs#Overview there's a section headed "Here is a more detailed discussion" which at point 5 says "CompressLevel has toggled on/off between backups. This isn't well tested and it's very hard to support efficiently. ..." So I'd probably rename my machines as far as BackupPC is concerned, and remove the old backups using the Web interface after gaining some confidence that they weren't needed. Another option might be to work on one host at a time. For example (first, stop BackupPC to be on the safe side) delete 'host' from your config.pl, add the same host with a different IP/ID, then delete all the files in pc/'host'/ and finally restart BackupPC. I'd hope for the uncompressed files for 'host' which are no longer needed then to be removed (eventually depending on config) by the nightly cleanups. Whatever happens I think if you try any of this then we on the mailing list would welcome notes on your experiences. -- 73, Ged. _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/
