if you select a directory to restore, netbackup
will have to read the entire ndmp backup image from tape to get everything in
the directory. it should still restore the directory and all
files/sub-directories beneath it, it just takes a longer time. if you
select a file or set of files (i believe up to 1024), then it will use dar, and
netbackup will be able to get to the files faster in the backup image. we
have restored a directory with 10 files in it, and it took 3 hours as it was a
1.5 TB backup image. we then selected only the 10 files and the restore
took 12 minutes. both restores did restore all of the
files.
We got ‘caught’ by the same
thing – found this in the NDMP Admin Guide:
Note File-level DAR
is supported; directory-level DAR is not
supported.
You need to select each file in
the directory or else the entire volume…..

Does anyone have any experience with this
configuration? I am having problems restoring although the backups work fine. If
I click a specific file or files the restore works, however if I pick the
directory only the directory is restored, none of the files. Any help will be
greatly appreciated.
