Required disk space for NetBackup restore?

Created: 16 Sep 2005 • Updated: 22 May 2010 | 5 comments

Does anyone know whether the NetBackup restore requires extra disk space to store temporary files during the restore process just as the backup does?

I'm not sure what you are refering to that NetBackup uses disk space for doing backups unless you are either using a disk storage unit or disk staging. Normal NetBackup backups to tape do not use additional disk space. It is all done with memory buffers.

Restores may temporarily use disk space if the file being restored is in use. On the next reboot the OS will move the file to where it should actually reside.

VERITAS ain't it the truth?

I'm trying to restore the System State and C: drive of a client and overwrite the current data on the client, but the restore keep failing due to out of disk space. That's why I wonder whether a restore requires certain amount of availabe disk space on the side or not?

Yes,
if you are very low on disk space, this will happen, because of the temporary storage for replaced files.
If you can move your pagefile or remove other files from your c drive to get enought space, it will probably work.
You must be VERY low on space?

Yes, the client only has about 1GB of unused space. I will look into moving the pagefile or anything else that can be moved.

Thanks eveyone.
