Fantastic, I will do the tests next week. Honestly I did not expect the change to get through so fast :-) Craig, thanks a lot for you wonderful work. And thanks Michael for the initial testing! Best regards, Pavel. Dne 14.3.2017 v 02:38 Michael Huntley napsal(a): > Works great, zero problems

I pushed bin/BackupPC_migrateV3toV4 to git. It uses the hybrid approach I mentioned - V3 backups still use the same forward deltas; this script only replaces the hardlinked backups in each directory with V4 attrib files (and MD5 digests). Usage: BackupPC_migrateV3toV4 [-p] [-v] [-h host [-n V3ba

mph, Actually we are based on drives only. I could make a huge 10TB tar and put it somewhere but the idea of conversion and having all the backupcs together... Anyway, thanks a lot for your suggestion, should the hybrid storage not perhaps make the way through I will head in this direction. B

Oh those pesky deltas! I slept on it; it's better to make a break with the past. I'm going to tar up the old data+hardlinks and put it to cold storage. Time is a finite resource so I'd rather move forward than get stuck in the weeds of the past. Pavel - have you considered using tar+tape to a

There are two options to implement this: - truly convert v3 backups to v4 format. This is quite complex since forward deltas (ie, incrementals) would have to be converted into reverse deltas; there are lots of cases to consider and testing them all would take a lot of time. The effor

Hi Craig - among the billion other things to do in life - is this reasonably possible? I looked at the perl and came to the considered conclusion, I'm just not a perl guy. However, it would be great to convert older backups to v4 - that would reduce my workload on BTRFS snapshops, etc. No har

2017-03-06 Thread Pavel Hofman
Hello, please is it possible somehow to script the BackupPC_backupDuplicate tool to be able to convert not only the last v3 backup to v4, but also all previous backups? I would run the script in the background. The intention is migrating from XFS to ZFS for server consolidation and I am afraid
