Note: This is not a recommended procedure. It should be used only in extreme situations and as a last step in attempting to restore data. This procedure has been used on numerous occasions with success.
First, figure out the fragment number and the block size needed.
# ./bpmedialist -mcontents -ev D0004
media id = D0004, allocated 09/21/99 14:19:, retention level = 1
File number 1
Backup id = jeckle_0937941543
Creation date = 09/21/99 14:19:
Expiration date = 10/05/99 14:19:
Retention level = 1
Copy number = 1
Fragment number = 1
Block size (in bytes) = 32768
Then work the tape:
ficus# tpreq -ev D0004 -a r -d dlt -p NetBackup -f /tmp/mytape
This issues a tpreq for media id D0004, the " r " is for read, the " -d " is density, " -p " is pool and " -f " is mount point.
