Hi all, I've recently started down to put on production use for zfs and I'm looking to how doing a backup of filesystem. I've more than one server to migrate to ZFS and not so more server where there is a tape backup. So I've put a L280 tape drive on one server and use it from remote connection.
The ZFS configuration and command to make a backup is the following: --- Client A Client-A# zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT tank 119G 50.0G 69.0G 42% ONLINE - Client-A# zfs list NAME USED AVAIL REFER MOUNTPOINT tank 37.4G 50.2G 36.7K /tank tank/zones 37.2G 50.2G 25.6G /opt/zones tank/[EMAIL PROTECTED] 11.6G - 25.0G - Client-A# zfs send tank/[EMAIL PROTECTED] | /opt/3pp/openssh/bin/ssh -c blowfish -l root server-backup <http://10.1.101.30> \(dd ibs=258048 of=/dev/rmt/1 obs=2064384 \) When I want to restore what I've dumped, I do the following: Client-B# zfs list NAME USED AVAIL REFER MOUNTPOINT tank 144K 66.9G 27.5K /tank tank/backup 24.5K 66.9G 24.5K /tank/backup tank/zones 24.5K 66.9G 24.5K /tank/zones Client-B# zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT tank 68G 148K 68.0G 0% ONLINE - Client-B# /opt/3pp/openssh/bin/ssh -c blowfish -l root server-backup \(dd if=/dev/rmt/1 bs=2064384 \) | zfs receive tank/zones stty: : Invalid argument cannot receive: invalid stream (bad magic number) select: Bad file number Client-B# What the trick?
