Hi all,
We're starting to provide CIFS service out of a FAS2040, and we want to establish conventional backups with our existing EMC Networker setup, or our other NetBackup setup.
If we use NDMP, is the folder/permissions data in the CIFS volume sucked across, with valid integrity, in the NDMP backups?
Our Networker servers are based on Linux. Can Networker attach to the CIFS share directly, and haul across the backups? (Maintaining share/security data per above.)
Otherwise, does the Networker/Windows client back up mount points? We could mount the CIFS shares inside a Windows VM, and run the Networker client there, right?
Thanks for the help!

I can comment on the Netbackup experience. I am not the backup guy, but we backup via /vol/blahblah.
It will backup the volume and any qtree's and retain the NTFS permissions. When you go to restore (we have a NDMP vol we restore to), when you are done with the restore, it lays the perms down, so if you dont have rights (like our backup guys don't), it lays down the perms, and I believe if you have any other restores in that location, the files also get the same perms as what was restored (if that makes sense).
Backing up via the network would work, but we backup 10's of millions of files, and having to crawl the CIFS file system is laborious and time consuming at best. You can try to use remote NDMP if your backup infrastructure is not directly connected to the filer(s). We try to keep our CIFS vols under 4 or 5 TB for backup considerations. The larger and more files in the vols, the longer it takes to backup.
Mounting the stuff in a vm would work, but is combersom at best, adding unncessary overhead on the underlying vm hardware (IMHO).
NDMP is our friend..
Just my 2 cents.

We are a networker-on-Linux shop with mostly Windows clients, and when we investigated CIFS with NDMP for backup, we found some of the limitations not good for us.
-- 0-9 backup levels is all you get, with 0 being a full and each following level capturing changes from the level before it. We usually do monthly fulls with weekly level 1 and incrementals in between, and like to stay flexible.
-- You can only restore to another filer. I had concerns at the time if you need 100% space to restore or if single file restore worked with NetWorker. I'll try to look this up.
-- EMC licensing for NDMP for a HA NetApp pair was grossly unfair at the time. There was a nice Celerra discount however… :\
CIFS on Linux works, and Samba is one of the most mature open source projects out there and even predates the modern Red Hat Linux distribution to a some degree. Would EMC support backing up CIFS shares with Linux? Maintaining ACLs -- Red Hat's ACL implementation is of the posix model, and does not map to Windows. You would likely be backing up the CIFS share with only the octal permissions that samba presents to the NetWorker client, but I haven't tested this.
Be prepared for a lot of overhead if you attach your share to a Windows or Linux client and configure this client in NetWorker. I would imagine SMB 2.0 improves this somewhat, but SMB is not known for peak workload throughputs.

I have used Networker to backup a filer via ndmp.
You can do single file restore if you turn on DAR. It adds a little overhead to backups. We rely on snapshots for restores and use tape for DR backups where we would we want as much performance as possible and so turn off DAR.
