I've been having trouble with backup/restores since day one and I'm hoping someone can help me out.
Our enviornment is a clustered 840 with ~3Tb of raw disk running 6.1.1R1 in a mixed environment. The backup unit is a storagetek L700 hooked to a Solaris 8 system with Netbackup 3.4. Each filer in the cluster is direct scsi connected to 4 drives (2 drives per scsi card). The library robot is attached to the solaris netbackup box, which is also the admin host. We are using NDMP.
Here are the issues:
- First the backups work. We had some issues where backups would not run and found that by default the OS does not have a dumpdates file. This prevented ndmp from backing up. We simply touched the file.
- I can't restore anything. I get a Permission Denied error from netbackup. I don't know if this is permission denied accessing the filer (although I can't see how... I can rsh from the box -and- backups do work) or permission denied writing the files. The restore request is for a simple directory on a mixed tree, the data has no acls. Root can mount the filesystem and do what it wants with the files directly. This is by far my biggest problem... can anyone help?
- After every backup there is a file structure left at the root of *every* volume. Every volume has an /etc directory with two subdirectories, /etc/oldmaps and /etc/tmp. There are subdirectories below these , Is this normal?
- Netbackup does stream backups. It sequentially backs up every volume. We have four drives per filer but it will not start the backups in parallel. I can force this by creating a seperate class for every volume. Is this the way to do it? Is there any netbackup / netapp white paper?
THANKS!!
We have 3 NetApp F740s with NetBackup 3.4 and our backups/restores are working fine.
Are you doing a restore to the filer? You can't do an alternate target restore to your Solaris server if that's what you are trying to do. If you can do a backup, that means you have it configured correctly with respect to root password on the filer.
For streaming backups, we have 'Allow multiple data streams' enabled for the NetApp class. Then you can either set the global attribute for max jobs per client (from the main JAVA gui window), or, what we do, is set it on a per client basis using the admincmd/bpclient command (-max_jobs option).

netbackup. I don't know if this is permission denied accessing the filer (although I can't see how... I can rsh from the box -and- backups do work) or permission denied writing the files.
