Copy DLT Tape

[Joseph Bague]

Hi all

How can I copy a Omnibackup (DLT) to another DLT using one DLT drive.

Thanks in advance
Joseph

Hi,
This is not possible, you need two drives. OmniBack don't support copying data between different media types (for example file device and DLT device).

Just an idea...
Is it possible to load data from the tape usind 'dd' command (and using correct omniback block size) to the file and then save this file to another tape using 'dd' and the same block size?
Why not?

Hi,
Eugeny,
There has been some questions about using dd for copying OmniBack tapes in the OmniBack forum. It seems to be very hard. Have a look at Frank Slotwegs answere in this thread:

Omnimcopy can only copy from one drive to another identical drive. Dd copies absolutely do not work for OB2. The one thing about omnimcopy that may not be obvious is that it is possible to copy from one DLT to another DLT drive even if they are on different hosts.
