HI all,
Compaq Tru64 UNIX V5.1 (Rev. 732)
Patch kit: T64V51AS0002-20001204 OSF510
We use vdump to backup all our system, including nfs mounted attached
storage (NetApp).
I have found when using vrestore, some restored files from the nfs system
are just full of null characters (found using od -a), although the file
itself is the correct length. The majority of files restore OK - but as
you guys and gals know majority is not good enough for a production system
=)
At first I imagined a problem with the tape media, but subsequent testing
vdumping to an ordinary local disk file gave the same results. It also
does not appear to be when a file is open during backup, because files
which I know are not open contain nulls, but other files which were likely
to be open can be restored OK.
I thought vdump was able to backup any mounted system, including nfs.
Has anyone come across the same problem with vdump/vrestore?
Should I adjust my backup strategy? - suggestions welcome!
Best regards / Mit freundlichen Grüßen
