Speaking for NDMP bacukps/restores from/to a EMC Celerra: Yes, if there
are any files in the subdir, it gets created. We got around the "no dirs
with DAR" prob by using
"bplist -C xxx -s xxx -e xxx -t 19 -R /<some_dir>/*"
pipe that to a file, do some perl magic on it and feed it to bprestore.
Also DAR doesn't work for more than 1024 files at a time so if it's a big
directory you have to split up restores. And last but not least you have
to be careful with some special characters such as [ or ] which have to be
escaped before fed to bprestore (or just filter them out and restore those
files from the GUI later). In our case it was worth the effort as it sped
up a restore from a whole day (running into the following days backups) to
a couple of hours.

RE: [Veritas-bu] time for NDMP restores
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
