Backing up Remote Systems

Alex Patel — Tue, 02 Nov 1999 11:14:04 GMT

Hi,
Could anyone please tell me how to backup a computer running HP-UX 9.0 from a
separate computer running HP-UX 10.20. If this task can be accomplished by SAM
it will be great.

Remote Backup from SAM or fbackup should be possible.

One of the following options should work:
1) Use NFS to remotely mount the directories to be backed up from the 9.0 Box
on the 10.20 Box. Then run SAM "Backup and Recovery" from the 10.20 box. When
setting up the backup scope make sure to set up Cross NFS mounts to "Yes".

2) At 10.20 it is possible to setup Automated Backups by specifying a remote
backup device. I'm not sure if this is available on the 9.0 version of SAM.
Assuming that it is the same as 10.X then you should:
A) Startup SAM
B) Select "Backup and Recovery"
C) Select "Automated Backups"
D) Choose "Add an Automated Backup" from the "Actions" menu.
E) Then Choose "Remote Backup Device"
F) Use "Specify Remote Backup Device" to specify the 10.20 Box and the
appropriate tape device file.

3) SAM is using br_backup which is just a wrapper for fbackup. Consult the man
page for fbackup on your 9.0 box. When specifying the -f option to select a
tape device file, you should be able to select a remote device. For example,
assuming the remote 10.20 box is named "remote" and the device file for the
tape drive is /dev/rmt/0m, a command like the following should work:
# fbackup -f remote:/dev/rmt/0m .....

If neither 2) or 3) seem to work, it is probably due to the lack of
functionality available at 9.0. That would leave 1) as your only viable
option. However, you could also update the 9.0 to a 10.X level to achieve the
increased functionality. After all, 9.0 can not be made Y2K compliant, so it
will not function properly in 2 more months anyway.

Just in case you are running 9.10 which can be compliant, ensure that root has
.rhosts capability enabled. the remote tape device in fbackup uses rmt which
will need the .rhosts file.

Also, if you do want to use a NFS mount remember that root gets mapped to uid
-2 unless you specify otherwise.
