[zfs-discuss] ZFS snapshot zvols/iscsi send backup
I'm looking to use ZFS to export ISCSI volumes to a Windows/Linux client. Essentially, I'm looking to create two storage ZFS machines that I will export ISCSI targets from. Then from the client side, I will enable mirrorings. The two ZFS machines will be independent of each other. I had question about snapshoting of ISCSI zvols. If I do a snapshot of ISCSI volume, it snapshots the blocks. I know the sending the blocks will allow from some from of replication. However, if I send the snapshot to a file, will I be able to recover the ISCSI volume from the file(s)? e.g. zfs send tank/t...@1 | gzip -c zfs.tank.test.gz Can I recover this ISCSI volume from zfs.tank.test.gz by sending it directly to another ZFS machine? Will I then be able to mount the ZFS volume created from this file and have my filesystem be the way it was? If I assemble the blocks like they were before, I assume it assembles everything the way it was before, including the filesytem and such. Or am I incorrect about this?

Yes. The send data stream is just that, a stream of data. If you want to archive the file, do a test receive first to make sure there isn't any data corruption. Will I then be able to mount the ZFS volume created from this file and have my filesystem be the way it was? Yes. -- Ian. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
