We're looking into this (NDMP backups) and the "can't restore a directory"
problem might be an issue.

If you want to restore a directory, then, you have to find every file from
that point down & restore it individually?  Will it create missing
subdirectories, ie:

restoredir/file1
restoredir/file2
restoredir/subdir1/file1
restoredir/subdir1/file2

...If the above was your list of files to be restored, does "subdir1" get
created?

Did you request to restore files or folders?   DAR is not supported for 
directory restores - so it is *very* important that you pick files to 
restore, and never folders.  Otherwise it scans the whole tape, even if it 
already found what you wanted.

[Veritas-bu] time for NDMP restores






Hi all.
 
it's been years since I've worked with NDMP much (NB 3.x and Auspex file 
servers), with 32 and 64 gig filessytems
so I'm re-learning everything with NetApp, NB5.0 and TB+ filesystems, and 
refreshing lots of old memories.
 
seems a restore, even of a couple files from a 600+ Gig FS backup (home 
directoy FS) takes HOURS....like 5-7 hours.
 
The progress monitor shows the tape mounted, positioned, etc, then sits 
there for hours with no KB/s or KB restored reported, then, bam, it's 
done.
 
this more or less normal?
 
If so, do you folks have SLAs that account for this kind of timeframe for 
restores?
or do you you snapshots exclusively for restores of user data and only use 
tape for DR?
 
Paul
