Backup's

ICT Infrastructure — Thu, 12 Sep 2002 09:20:29 GMT

I currently run a cpio backup and i am finding that it is too slow and there is not enough time time to run a full system backup.

Could somebody please give me some alternatives and commands i will need to run them.

Thanks

Hi

ftio is similar to cpio but faster.
fbackup is the HP-UX standard backup utility.
You can check the man pages for this two programs.
But if you have more advanced needs I will recommend you to look at a "real" backup program (for example OmniBack).

PS
It is not sure it is cpio that is the bottleneck, it can be tape device , disk/filesystem etc. as well.

We switched from using cpio to ftio and it halfed our backup times. ftio give you multiple processes to read and write. It is also compatible with cpio and costs nothing. You also get a header when you read the tape which give you information on the backup like the date etc.. which is useful.

If possible I'd recommend using fbackup, but if you want something that fits into your existing setup quickly and shouldn't take much thinking about in terms of changes then use ftio.

Are you using the default nice value and running in the background? This will default to a nice value of 24.

If you don't care about swiping processor cycles, in addition to using ftio you could start the ftio process with the nice command, maybe:

nice --24 ftio .... &

This will set the nice value to 0 (highest priority) and improve the time it takes.
