Solaris

Making the backup...

    * Find a tape and load it into your tape device. The tape device in 
this exmaple is /dev/rmt/0
    * You may want to bring the system down to single user to make the 
system as quiet as possible.
    * Keep a record of how the partitions are set up by going into format 
and copying the table to a flat file or printing it out. Just put it 
somewhere that you can have access to it in the event that the disk's 
partitions are totally lost. Below is an example of what you want to 
record. To get to this information just su to root, type format, then pick 
the disk you're backup up, then type in partition, then print.

    * For even more record keeping grab the /etc/vfstab file and do a df -k 
to confirm what slices are being used for what. Either print this or keep it
 in a file somewhere accessible for when the server in question is not 
available.

          o Backup each of your separate file systems. In this case we have
 /var, /usr, /opt and /. Remember or write down the order in which you do 
each backup.
          o ufsdump 0uf /dev/rmt/0n /
          o ufsdump 0uf /dev/rmt/0n /var
          o ufsdump 0uf /dev/rmt/0n /opt
          o ufsdump 0uf /dev/rmt/0 /usr
          o That is the extent of ufsdump. After this you will have a good 
backup, so keep that tape handy.
       
==============================================

      To do the restore ...
          o Get the server in question to the OK prompt
          o boot cdrom -sw ( s means single user, w means no windows )
          o format ... to see if partition table is the same as it used to be. 
If not, re-partition.
          o Time to build a new file system on each of the partitions that need it.
          o newfs /dev/rdsk/c0t0d0s0
          o newfs /dev/rdsk/c0t0d0s3
          o newfs /dev/rdsk/c0t0d0s4
          o newfs /dev/rdsk/c0t0d0s5
          o Do a files check on each of the new file systems.
          o fsck /dev/dsk/c0t0d0s0
          o fsck /dev/dsk/c0t0d0s3
          o fsck /dev/dsk/c0t0d0s4
          o fsck /dev/dsk/c0t0d0s5
          o Do the actual restore, restoring one file system at a time. Make 
sure you remember which backup is for which partition. For instance, if 
the first file system you backed up was / , then remember to restore the 
first backup to the appropriate slice. See below.
       
          o mount /dev/dsk/c0t0d0s0 /a
          o cd /a
          o ufsrestore rfsvy /dev/rmt/0 1
          o cd /
          o umount /a
       
          o mount /dev/dsk/c0t0d0s3 /a
          o cd /a
          o ufsrestore rfsvy /dev/rmt/0 2
          o cd /
          o umount /a
       
          o mount /dev/dsk/c0t0d0s4 /a
          o cd /a
          o ufsrestore rfsvy /dev/rmt/0 3
          o cd /
          o umount /a
       
          o mount /dev/dsk/c0t0d0s5 /a
          o cd /a
          o ufsrestore rfsvy /dev/rmt/0 4
          o cd /
          o umount /a
       
          o Install the boot block.
          o cd /usr/platform/sun4u/lib/fs/ufs
          o installboot ./bootblk /dev/rdsk/c0t0d0s0
          o The restore is now finished. If this is a test to restore a server 
that is still working, you would need to change the IP of this 'test' server 
or disconnect the network cable.  Reboot the server and it should come 
up.
