I have disabled the DAR option by removing the DIRECT=y application information and now the restores are faster even though all the backup volume is read from tape. NetApp tech support says that DAR wasn't designed for tape backups but for disk backups.
I am backing up to SDLT320 tapes. Our NetWorker serveur is SCSI attached to a StorageTek L700 library. Our NetApp servers are gigabit ethernet attached to the same switch on which the networker server is attached.
What can we do to significantly improve our NDMP restore performance?
Thanks.
I asked NetApp and they told me we don't have that bug with our backups.
Sometimes when I start an NDMP restore, NetWorker loads the required tape but then it stays on "Ready for reading, idle" for a long time before starting to actually read the tape. I wondering why does it do that.
Do you...
Hello,
We have a newly installed Windows 2003 member server with the main role of print serving. I've noticed that by default the print spooler is stopped and in manual start. I've started the service, installed our 60 network printers and changed the service to automatic start. I've then...
Hello,
We were backing up our NetApp filers by UNC about 6 months ago but in order to optimize performance we decided to implement NDMP backups using NetWorker 7.2.
We have had a very important performance increase for the backups but the restores were much slower than before. Most restores...
Wow, i've installed sudo in our server and it works perfectly! Now our data manager can migrate the data into our NetApp Filer and keep the original file permissions without using the root account. Thank you very much daFranze for your tip. I know it's dangerous to allow him to use mv as root...
What if I authorize a regular user to run the "cp" and "mv" commands as root (via sudo), would I be able to accomplish my goal?
Thank you very much for your help.
Hello,
I would like to allow a regular user to copy files from other users and keep the original permissions without giving him the root access.
I have tried to copy a folder that belonged to a service account with the '-pr' switches but the resulting folder will have my ownership instead of...
The level is "incr" (incremental).
The amount of data does not represent a full backup but about 80% of it.
Here's one line of the savegroup completion log file:
"fileserver1: D:\ level=incr, 425 GB 25:36:38 1460111 files"
Thanks for your help.
Hello,
Our incremental backups started behaving stragely since about a month ago. We have 2 NetWorker clients (file servers) that backed up around 30 Gb of data daily in our daily incremental group and now these same clients backup around 200 Gb and 400 Gb respectively every day. I doubt that...
