Home -> Community -> Mailing Lists -> Oracle-L -> Re: RMAN and NFS
Michael,
Why not have the best of both worlds.
Store the backups on diskA, NFS mount to diskB, on the new server NFS
mount to diskB, and transfer the backups to diskC.
That way you have the backups available for restoral and they can also
be located on a commonly NFS'd disk between the servers.
Disks are cheap remember? and then the burden of multi disk managements
falls on the sysadmin.
The use of NFS is/ was/ could be a problem if the server or network
have problems but usually it is reliable and an inexpensive method
of obtaining disk storage. We use to use NFS when the SCSI disk drives
were 1 GIG each and about the size of a shoe box. Only 16 physical slots
on the 2 SCSI card server and we needed more storage. The method was
reliable and a cost effective method of solving a problem.
Congrats on the move to RMAN.

I am looking to move to RMAN as a backup tool and away from my shop's standard of BMC sqlbacktrack.
This is certainly a popular topic on this list, as I've seen many
posts
related to this specific situation.
One thing I notice is that we get several requests to duplicate or
"clone" databases, and I understand and have used RMAN to easily
accomplish this. However, the recommended method for doing so
(according to the manual I have read) is to use a NFS to accomplish
this
(by storing the backups in a directory shared by source and target).
My network and OS support folks swear that this is extremely insecure, and refuse to support it.
I have read about some architectural models that suggest ALL databases
be backed up to a central, networked server and disk (we much prefer
to
keep current backups on disk for reduced MTTR).
Can anyone on this list give me ammunition to appeal to my network and OS support people to reconsider their stance?
(BTW - when applications require NFS mounts - they often get their way
-
ironic, isn't it???)
