backup / restore via DDS4 tape

HP-UX B.11.11 9000/800/rp7410

Hello All,

I would like to know what's the best method of backing up & restoring some filesystems from server to another? I did make an ignite tape, but system I'm restoring to has is a different model (9000/800/L3000-7x) with
different size drives in vg00.

My tape drive is DDS4 ( I think it stores 40G )? The largest filesystem I'm working with is 32G of data:
/dev/vg01/u01 122880000 32957712 88517312 27% /u01

I saw a few different methods commands :
1) dump command:
/usr/sbin/dump 0udsf 20480 30000 /dev/rmt/0mn

2)tar command:
tar -cvf - <.mountpoint> | gzip > /dev/rmt/0m

What are your thoughts.
Thanks
Jerry

tar.

or

gnu's tar which can also do data compression:

Jerry, it's hard to beat tar for reliability...
If you search here in the forums for vxdump, there's some good examples of that one too.

First of all, make_tape_recovery was never intended to a be backup tool but rather a system recovery tool and works best for vg00 only --- preferably to the same machine. For ordinary backups -- between HP-UX boxes -- it's very hard to beat fbackup/frecover. It can be configured to be much faster than tar or cpio and does not have the 8GB file limit that even the Gnu version (or patched HP versions) of tar imposes. Vanilla cpio maxes out at 2GB files. The downside of fbackup is that it is not portable outside the HP-UX world.

Serious backups demand serious solutions like DataProtector.
