Operating Systems Solaris Solaris 11 - how to backup and restore system disc Post 302560659 by RychnD on Friday 30th of September 2011 12:26:44 PM

Thank you for your answer.

I have in fact experimented with this for a while already and created a shell script for automatic backuping of snapshots. I was however not able to restore the backups correctly - more specifically, I did not succeed in making the computer boot from the restored disc.

I did even create a topic about that on this forum earlier. I described the steps I took to restore the snapshots and what the results were.

I have experimented yet a little more since then but still did not succeed and I have no idea what to try anymore.

Besides the steps that I described in the other topic I did also try to install the system to a new disc in a standard way and restore just the important filesystems (the system root and the user directories) but that did not work either.

That's why I thought the way I've chosen might be completely wrong and that I should create a more general question in order to find out the ways other people do that.

On my system hard disc I have the following filesystems:
  • rpool
  • rpool/ROOT
  • rpool/ROOT/solaris (this is the system root directory)
  • rpool/export (this is the root of user home directories)

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. SEE ALSO
