Hello all,
does anybody have experience with using NetBackup with Netapp filers (using
NDMP) ?
This time it's a question about best configuration.
let's say we have 4 volumes in one filer and 1 volume in the second filer.
so we need to backup the 5 volumes.
i think about creating 2 classes, one per filer.
and only one volume pool to serve both filers.
but in this way each set of tapes (group) will take the backup from all the
5 volumes sequentially.
so in this case if i need to restore a file from the 5th volume it will need
to go through all the tapes till it reaches it.
also what if one tape of this set is damaged, will this make all the set
(group) unuseful ?
this configuration reduces the number of tapes per group, and it looks
simple.
but another way appears, to create 2 classes, one per filer (no change)
and create one volume pool per netapp volume , so create 5 volume pools,
with initially one tape in each and create
a scratch pool to serve all the pools in need for tapes.
but in this case the number of tapes used will increase.
i don't know if it is that serious to choose between the 2 configurations,
but i know it may impact all the system in the future.
So does anyone have a better idea, or better experience with this stuff ?
Appreciate your response
Ahmed
