Can a WORM disk be copied?

[Jason Berendsen]

HP-UX 11.00

I imagine this can't be done but, is there a way to copy the data on one WORM disk to another WORM disk. We are using Filenet software to write to the WORM disks, and are looking for a way to make a copy that can be sent off-site daily. Unforunately Filenet's solution to this is very costly.

Any ideas?

You can probably do this.

I'd look into the dd command.

More likely you can copy the data to a regular disk and then copy it using the worm utility for hpux to the blank worm drive.

Steven,

Can you give me a little more information. I've looked into dd going from one WORM to another which I couldn't get to work. If I use dd to copy to a standard disk how do I copy it to the blank WORM? What is the HP-UX WORM utility you speak of?

Thanks,

Jason

Filenet!

With plasmon?

WORM = Write Once Read Many.

I need more information about the sizes of data. We had a DR site for filenet on plasmon drives with two issues: The device file names changing during reinstalls and the Filenet file format.

The good thing is WORM is 90% reading of data and 10% writes. So duplicate the entire database once and sync it up occaisionally with the small changes that take place.

Michael,

We are using 5.2 gig 5 1/4" opticals, an HP SureStore 1200EX. It currently takes us about 2 weeks to fill up a Filenet tranlog. Meaning we can't send it off-site for this period, opening ourselves up to a possible loss of 2 weeks of data in a disaster. We are trying to find a way to do a copy of the current tranlog daily to send off-site. We would do this on re-writable media, where the actual tranlog would be on WORM. Filenet has a disaster recovery solution, but at this time it is cost prohibitive. Since you are working with Filenet software have you any ideas?

Thanks,

Jason
