NFS mount-point and backup question

[Maarten van Maanen]

We have a K370 running Oracle on a 12H.
We have also just set up a D370 with five 9Gb disks for running tests. However, with only a 8Gb DAT the D cannot make a proper backup. Volume-names on the D are the same as on the K. Would it be possible to set up NFS on the K and make a backup on the DLT-drive of the K to include the NFS-mountpoints ? (Have never used NFS before). My other solution is to just CPIO all D-data to the K (have just enough room on the 12H) and to the backup from there.

Hi,

for your purposes i would recommend using fbackup because it can handle remote (tape) devices.

Andreas,

I have tried using fbackup with remote device from the D but this is EXTREMELY slow. Part of this will be due to the fact that the five 9Gb disks on the D are SE-SCSI and are form a JBOD. The other problem is that I have to make my production-backup in the same time-frame as the test-backup. To the solutions I can think of is either NFS or ftp/cpio the data from the D to the K prior to the actual backup.

You can also use dump or vxdump. It is much more efficient than fbackup and does very well remote tapes. Its counterpart restore/vxrestore has a user-friendly interactive interface but it cannot retrieve selectively without reading sequentially. fbackup can access individual files by spooling to it but it sucks when you don't have time.
