Hi, I managed to get zfs backup type working. Only problem is it is also very very slow. Currently I only see around 1Gbyte/minute. I need to do some more investigation where the bottleneck is. Once I got backup and restore working at acceptable speeds (3Gbyte/min) I will write a little howto. Also recursive backup is now working.

That is good news. Is there maybe already a beta or nightly build available for this new NDMP setup that supports DAR? Maybe I will try backup format = zfs in the meantime and see if that is faster. I was just about to reply to my previous post but then your message arrived. :) >> I think I’m making progress. I enabled debug logging on the bareos server >> and I enforced direct = y for the client. Now I see this in the logs: >> NDMP4_LOG_WARNING id=26 message='Cannot do direct access recovery. Some >> 'fh_info'es are not valid. I know that I shouldn't set that DIRECT meta parameter I was just trying to enforce it. :) Another strange thing with ZFS is that I can't get it to work recursively. e.g. Folder1 has subfolders: Folder2 Folder3 Etc. If I put File = Folder1 In the config file it will only do a backup of Folder1 but no subfolders. I tried setting meta parameter recursive = y but It didn't help. Maybe it's because the snapshot that is triggered by NDMP is not recursive?

DAR is not supported in Bareos 16.2.x, see http://doc.bareos.org/master/html/bareos-manual-main-reference.html#RestoreAlwaysTransfersTheFullMainBackupFileToThePrimaryStorageSystem Bareos 17.2 will support DAR, however the NDMP setup will be different. Information about this should be available until or at least at http://osbconf.org/, at the end of this month. > And besides using tar or dump I read that zfs can also be used as > backup type. Is this supported? In principle, the NDMP devices itself cares about the backup format. Bareos retrieves it from the device on backup are sends it back on restore. However, most tests on Bareos are done using the DUMP format. regards, Jörg -- Jörg Steffens [email protected] Bareos GmbH & Co.
