Backup of complete system with make_tape_recovery?

Rolf Modin — Wed, 30 Jul 2003 08:37:05 GMT

Can I make a total backup of my complete test-system with make_tape_recovery? I would like to just have to boot from the tape to get the system back to a standard starting point?

For instance:
make_tape_recovery -x inc_entire=vg00 -x inc_entire=vg01

Regards
Rolf

I think ignite-ux is for O/S backup, eg.
# /opt/ignite/bin/make_tape_recovery -Av -x inc_entire=vg00
to backup whole vg00, for other application and data, you need to use other utilities such as tar, fbackup, cpio...

I remember there is a thread discussing about full backup vs ignite-ux:

Hi Twang,
initially make_recovery was only a system recovery tool.

New version, called make_tape_recovery/make_net_recovery, also allow for a full system recovery, including the content of vg outside vg00, if desidered.

Tape must be large...

Rolf sintax is correct.
I suggest, just in case, to check latest patches of pax, they are always raccomended.

Thanks Massimo,
I see, I think we will consider using make_tape_recovery for full system recovery if it can include other VGs.
One more question, does it support multiple tapes backup? because we are currently using DDS4(40GB).

Hi Twang,

Its does support multiple tape option, as one finishes it asks for another volume.

Do understand that you can use Ignite to back up a whole system.

Two things to understand.

1) It won't do files bigger than 2 GB. Even if you install the pax patch to bring it up to 8GB, it won't be able to restore the big files.

2) open databases will not back up properly. You will need to close or shut down the database to get a clean backup.

Thanks Rajeev, SEP,
There are serveral oracle instances running on our site, some of them are for reporting purpose(datafile size < 2GB), currently I stop them at night and take a cold backup. Because they are running on different servers, I have to run ignite-ux for OS backup periodically.
Now I will consider to change backup strategy to use ignite-ux for backing up both OS and datafiles at the same time.
Of course, for other OLTP, I will not apply this approach.

I just wanted to add that w/ hpux 11i you'll want the latest pax patch to avoid pax failing if it attempts to archive any single file larger than 2GB.

-from patch text-
Symptoms:
PHCO_28414:
( SR:8606279428 CR:JAGae43481 )
Any attempt to backup a file of size 2GB or greater
using pax(1M) results in the following failure.

> 2GB. Not Dumped
