Local Full Backup and Restore ZFS

Hi men,

I'm testing for my backup&restore job with ZFS.

My server have two disks. I wanna do backup&restore job like ufsdump utility:

Disk0 is rpool(root zpool) and disk1 (backup zpool) will be stored full backup replicates. When rpool zpool have problem, i can "boot cdrom -s" and use my full backup replicate to restore my OS on disk0.

This is a example i read:

Code:

For example:
# zfs send tank/gozer@0830 > /bkups/gozer.083006
# zfs receive tank/gozer2@today < /bkups/gozer.083006
# zfs rename tank/gozer tank/gozer.old
# zfs rename tank/gozer2 tank/gozer

How can i do above commands in my circumstance? I did "zpool import " command but mount point of zpool cannot mount.

Code:

ok>boot cdrom -s
# zpool import backup
cannot mount '/backup': failed to create mountpoint
# zfs list
NAME     USED  AVAIL  REFER  MOUNTPOINT
backup  8.90G  58.0G  8.90G  /backup
# zpool import rpool
cannot mount '/rpool': failed to create mountpoint

# zfs list
NAME                            USED  AVAIL  REFER  MOUNTPOINT
backup                         8.90G  58.0G  8.90G  /a/backup
rpool                          9.79G  57.1G    94K  /rpool
rpool@0602                         0      -    94K  -
rpool/ROOT                     4.79G  57.1G    18K  legacy
rpool/ROOT@0602                    0      -    18K  -
rpool/ROOT/s10s_u7wos_08       4.79G  57.1G  4.78G  /
rpool/ROOT/s10s_u7wos_08@0602  3.26M      -  4.78G  -
rpool/dump                     4.00G  57.1G  4.00G  -
rpool/dump@0602                    0      -  4.00G  -
rpool/swap                     1.00G  58.1G    16K  -
rpool/swap@0602                    0      -    16K  -

I am muddling now, zfs is so complex. Please suggest my case or i should try other way to do full backup&restore?

Thx men!

vgcfgrestore

VGCFGRESTORE(8) 					      System Manager's Manual						   VGCFGRESTORE(8)

NAME

       vgcfgrestore - restore volume group descriptor area

SYNOPSIS

       vgcfgrestore [-d|--debug] [-f|--file filename] [-l[l]|--list] [-h|--help] [-M|--Metadatatype1|2] [-t|--test] [-v|--verbose] VolumeGroupName

DESCRIPTION

       vgcfgrestore  allows  you  to  restore  the metadata of VolumeGroupName from a text backup file produced by vgcfgbackup.  You can specify a
       backup file with --file.  If no backup file is specified, the most recent one is used.  Use --list for a list of the available  backup  and
       archive files of VolumeGroupName.

OPTIONS

       -l | --list -- List files pertaining to VolumeGroupName
	      List  metadata  backup  and  archive  files  pertaining  to VolumeGroupName.  May be used with the -f option.  Does not restore Vol-
	      umeGroupName.

       -f | --file filename -- Name of LVM metadata backup file
	      Specifies a metadata backup or archive file to be used for restoring VolumeGroupName.  Often this file has been created with  vgcfg-
	      backup.

       See lvm for common options.

REPLACING PHYSICAL VOLUMES

       vgdisplay  --partial  --verbose will show you the UUIDs and sizes of any PVs that are no longer present.  If a PV in the VG is lost and you
       wish to substitute another of the same size, use pvcreate --restorefile filename --uuid uuid (plus additional arguments as appropriate)	to
       initialise  it with the same UUID as the missing PV.  Repeat for all other missing PVs in the VG.  Then use vgcfgrestore --file filename to
       restore the volume group's metadata.
