Well I'm so impressed with zfs at the moment! I just got steps 5 and 6 (form my last post) to work, and it works well. Not only does it send the increment over to the backup drive, the latest increment/snapshot appears in the mounted filesystem. In nautilus I can browse an exact copy of my PC, f

Thanks Edward, you understood me perfectly. Your suggestion sounds very promising. I like the idea of letting the installation CD set everything up, that way some hardware/drivers could possibly be updated and yet it still work. On top of a bare metal recovery, I would like to leverage the incr

Thanks Cindy for the links. I see that this could possibly be a replacement for ufsbackup/ufsrestore but unless a further snapshot can be appended to the file containing the recursive rootpool snapshot, it would still regress from the incremental backup that ufsbackup has. It would take a long

[zfs-discuss] Best practice for full stystem backup - equivelent of ufsdump/ufsrestore

2010-04-28 Thread Euan Thoms
I'm looking for a way to backup my entire system, the rpool zfs pool to an external HDD so that it can be recovered in full if the internal HDD fails. Previously with Solaris 10 using UFS I would use ufsdump and ufsrestore, which worked so well, I was very confident with it. Now ZFS doesn't have

[zfs-discuss] ZFS clone destroyed by rollback of it's parent filesystem... recoverable???

2009-08-05 Thread Euan Thoms
I created a clone from the most recent snapshot of a filesystem, the clone's parent filesystem was the same as the snapshot itself. When I did a rollback to a previous snapshot it erased my clone. Yes it was really stupid to keep the colne on the same filesystem, I was tired and wasn't thinking

[zfs-discuss] Recovering files after zpool create -f

2008-07-30 Thread Euan Thoms
I accidentally ran 'zpool create -f' on the wrong drive. The previously zfs formatted and populated drive now appears blank. The operation was too quick to have formatted the drive so it must just be the indexes/TOC that are lost. I have not touched the newly created filesystem at all and the dr
