Re: How to take a full backup on HP UX 10.10

Shalom Vijay,

its a two step process.

Go into the deep dark basement and find an application cd and install the latest version of Ignite possible.

Use make_recovery or make_tape_recovery to make a backup of the boot volume group, vg00.

Then use fbackup to back up the rest of the system.

This system is so far out of support I have difficulty putting it into words.

Though I have minimal experience with HP-UX 9.04, I'm not sure what the state of fbackup was with that release.

I know newer fbackup has no problem backing up 10 GB of data.

I suppose if you have a network connection you can open up an NFS share and let some other modern tool back up the data to a high speed tape.

By itself, fbackup backs up the data, but not the system.

Vijay,

Well, I did not even knew what a computer was when 10.10 was around, but what about using omniback to backup those 10GB.

Jaime.

Hi Vijay:

You most certainly can use 'fbackup'. If you need a refresher, simply examine the manpages for 10.20:

http://docs.hp.com/en/B2355-90129/fbackup.1M.html

While support for largefiles appeared in 10.20, you shouldn't have any *file* larger than that. The overall size of the tape archive is immaterial.

Regards!

Re: How to take a full backup on HP UX 10.10

Hi Steve,

Thanks for the quick response,

Let me explain you the situation here,
We have planned to have a Dailybackup of the data on this 10.10 system and we do it using a common script (script uses fbackup command)which is used for other boxes as well and they run on 10.20 & 11.00, i dont see any issues with the newer versions but seems in 10.10 fbackup does not work and tar does not support more than 2 GB.

And problem here is i need to go for a big list of approvals for any new addition or changes on the box :) i think u can guess the process in production environment .

So i am trying to find out is there any other way by which i can do a full data backup.

Regards,
Vijay

Hi (again) Vijay:

Please post the command that you are using and the error or symptom that you obtain that prevents you from getting a full backup.

Regards!

Hi:

Well, a DLT7000 tape drive was not supported on 10.10 as I recall!!!

Hi,
Since your backup routine use fbackup, to stay compatible (I remembered seeing fbackup back in hpux 8.xx) with what works, that is your 10.20 and 11.00 environments, I would suggest you to mount what you wish to backup on a 10.20 remote box using NFS and the -f option of fbackup...


All the best

Re: How to take a full backup on HP UX 10.10

fbackup is the correct command for data backup. But that tape is useless if the boot disk is dead. You must regularly use the Ignite make_recovery program, perhaps once a month or so.

fbackup works just fine and is completely compatible with the files and filesystem sizes on your box. As mentioned, tar (and cpio, etc) are unuseable for large files. I would not recommend NFS because large files do not work in 10.10 NFS and the performance of NFS is far below most modern tape drives.

The real problem is your tape drive. 10.10 never had any support for a tape drive like this and there are no patches. Now tar may work for the DLT but fbackup is a high performance tool and needs to know specific details about the drive. Without DLT 7000 support in fbackup, it will likely fail. The best drive you can use is a DDS2 or DDS3. As with all modern tape drives, you MUST use a config file for fbackup -- otherwise, the backup time will be much longer than necessary.

As far as 10.10 and approvals -- because this is a "production" machine, everything running on that system is at serious risk due to the obsolete operating system. Unsupported tape drives are just a small symptom. You have security issues that cannot be addressed due to lack of patches as well as many other problems. And calling HP for help will result in the standard response: "obsolete and unsupported" That should motivate management to make immediate plans for migration. The standard answer "if it ain't broke..." has already failed because someone made a change to this system by adding a tape drive from the future (relative to 10.10).

Re: How to take a full backup on HP UX 10.10

Hi All,

Thanks for all ur inputs,
Strange that i am able to do a small backup with cpio on the DLT7000 attached to my box, and i have no choice than taking a backup using CPIO, But i think CPIO does not support more 2GB files and also as know its taking a lot of time but seems i have do it this weekend :(

Thanks & Regards,
Vijay

Re: How to take a full backup on HP UX 10.10

Correct. cpio (and tar and dump and pax, etc) cannot ave any file larger than 2Gb. As I mentioned, the legacy backup tools do not interact directly with the tape drive so generic writes will work OK. fbackup needs to talk directly to the tape drive to add highspeed setmarks and other special tasks.
