RE: snapinfo -- exchange on netapp
by Benn, Paul 05 Apr '06

05 Apr '06

Hi Toasters, It has been a while since my last post to the list but I wanted to echo my private reply from last week to the Toasters list for everyone's benefit. The SnapInfo directory can reside on its own (separate) LUN or on the same LUN with the Exchange transaction logs. What SnapManager uses this directory for is to store metadata corresponding to each backup set. In addition to that, SnapManager copies the transaction logs to the SnapInfo directory as part of its backup process. This way, you can, for example, use an old backup and still restore up to the minute of failure. What SnapManager does is restore the older database from snapshot and then replay all of the logs that it has stored plus any live logs that were generated after the backup. There would need to be a contiguous set of logs available, of course. With respect to your LUN and volume layout, I would encourage you to work with your NetApp technical sales representative to have them run your configuration through the "Exchange Sizer" that they have available. All variables from your particular environment will be collected and then fed into the sizer. This will ensure proper data layout and performance of Exchange as well as the NetApp storage appliance. The NetApp technical sales representatives have been trained on collecting the correct Exchange specific and NetApp specific data to put into the sizer. There are some sizing formulas and guidelines in the Administrator's guide but the sizer takes more than disk space into account when sizing a system. Please pardon my delayed response to the list but there was a reason for that. SnapManager 3.2 was posted to the NOW site today and in this release there are some new features relative to this discussion on sizing. These new features (a subset of all the new features in 3.2) are: * Fractional space reservation policies * Copy-less transaction log archiving * Option to not backup logs that have already been truncated by Exchange Here is a link to the new version for those of you with NOW access: http://now.netapp.com/NOW/download/software/snapmanager_e2k/3.2/ Regards, Paul Benn SnapManager Development Team Network Appliance > -----Original Message----- > From: Willeke, Jochen [mailto:Jochen.Willeke@wincor-nixdorf.com] > Sent: Wednesday, March 29, 2006 8:01 AM > To: toasters(a)mathworks.com > Subject: snapinfo -- exchange on netapp > > Hi everybody, > > we are setting up an exchange 2003 system on a filer.

Question re NDMP backups, snap vault.
by Warkentin, Grant 04 Apr '06

04 Apr '06

Have a situation I do not fully understand. Have an NTFS volume - contains mostly home drives. This volume is snapvaulted to a nearstore. The nearstore is backed up via NDMP. Had to change the ACL at the volume level (boss's orders). Granted an existing group change access. I knew this would increase the size of the backups due to changing ACLs on the whole volume. What I don't understand is that the size of the incremental backups have not gone back to "normal" since I made the change. Thoughts?

RE: volume space & ndmp backups issues
by Glenn Dekhayser 04 Apr '06

04 Apr '06

I would think that a good portion of your backup time is the ndmp scan prior to the backup. Not sure anything will help with that. I would think the best way to accomplish backup in the shortest time is to do volume level snapmirrors, which don't care about files. But, barring that- Is your NDMP backup going to a FC tape library? Or SCSI-attached? Or Three way? Also, what onTAP are you running? Perhaps if you went with a large aggregate you'd be better off in all cases. Glenn (the other one) -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of George Kahler Sent: Tuesday, April 04, 2006 10:45 AM To: toasters(a)mathworks.com Subject: volume space & ndmp backups issues I have a space and a backup (ndmp) issues with one of my volumes that is dedicated for mail in 'maildir' format (one message per file). I'm looking for suggestions from people on alleviating the space issue and possibly suggestions on the ndmp backup of this volume. I'm thinking that these two might be related. filer#1:/vol/maildir (14 x 72 GB disks) 2 qtrees: ugrad (undergrad students) grad (grad students) backup: (nightly incr. on an average backs up about) 11GB , 6million files, runs for 7 hrs filer#2:/vol/maildir2 (14 x 72 GB disks) 1 qtree: emp (employees) backup: (nightly incr. on an average backs up about) 8GB , 5million files, runs for 1.5 hrs All 3 qtrees have the same 2 level directory tree structure (as suggested by NetApp) and a common hashing algorithm is used to create 'home directories' in these qtrees. The top directory contains sub-directories from 0-to-f. Each of those directories contain sub-directories ranging from 00-to-ff. So a persons home directory would be something like: /vol/maildir/grad/2/75/dummy I need more space for the filer#1:/vol/maildir volume. Q1: should I just expand the volume onto more disks ? having more spindles might speed up the backup ? Q2: should I separate the 2 qtrees (u/grad) into their own volumes (14 x 72 GB each) to give each more space ? having only one qtree to scan , ndmp might run that much faster ? Thanks for any suggestions. George
