I asked the following on the NOW Backup Community Forum but I haven't yet had any reply. Can anyone help, please?

I have upgraded to ONTAP 7.0.1R1. I shall use ndmpcopy to copy vol2 to a new vol2flex- there's enough space. I shall remame vol2 to vol2trad and vol2flex to vol2. vol2 contains files accessed by CIFS.

We run nightly ndmp incremental backups (Netbackup, Windows).

1. Will the backup after the volume renaming be as normal (because most file modification times are still prior to the last incremental) or will we get a backup of everything (because some archive status bit shows none of the files have been previously backed up)?

2. To migrate, I may, in the event, do a level 0 ndmpcopy on a live system followed by a level 1 ndmpcopy with the volume restricted. Does this make a difference?

3. Later, I shall handle vol1 which has files accessed by both NFS and CIFS. Will the situation be different on this volume?

4. If a "level 0" backup is going to be produced, is there some way of avoiding this or are there good reasons why we should want to get a full backup?
