FACT(s) (Environment):

Compaq Tru64 UNIX 5.1
Progress 9.1C

SYMPTOM(s):

probkup failing with error 5057:

Backup failed due to EOF during next output device request. (5057)

Using a Compaq DLT device that should be able to backup 40GB uncompressed and up to 80GB compressed.

Using probkup -com -red.

CAUSE:

The tape device may in fact be really running out of space for the following reasons:
1. The use of -com could cause problems when the hardware compression is also running on the tape machine: it may be the case that the hardware compression functions less efficiently on the "pre-compressed" data sent by probkup.
2. There was also a bug with certain tape machines of this kind such that the hardware compression went down from 35/70 to 20/40; fixed in Tru64 64 5.1A patch kit 5. This bug in combination with the possible problem of the hardware compression interacting with the Progress probkup -com led to the 5057 error.
3. The use of -red also increased the size of the backup.

FIX:

1. Ensure that the correct and latest patches and drivers are installed for the tape machine.
2. If using hardware compression on the tape machine, run probkup without -com.
3. Check if -red is required.
