Data Protector Client for OpenVMS V5.5 (DP V5.5)

Here another LOGFILE:

Showing the same disc to the same tape with the OpenVMS Backup (V7.3-1)

And it uses with /LOG enabled just 7 Minutes...

Given your logfile of DP it seems it will do the backup file-by-file. If just examining what files to backup takes about an hour and a half, I'm not surprised that writing to tape would use just one hour extra....

If image backup is no option, the only solution (using DP) seems to be to play with it's buffering - if possible. Otherwise, if you have to use DP for your backup, consider another approach. It may be more costly in terms of processing, but you could win (dramatically) in time creating the backup.

(A personal note: A backup product to be used on VMS would not just have at least about the same execution time, it should also use the standard available utilities and therefore faciliate VMS-specific strcutures. If your statement on the system disk is true, and usage of DP would require WRITEBOOT after backup, I have severe doubt on DP and I would drop the product immediately and completely, for usage on VMS systems)
