Disagreement can lead to minds being changed. Is there ever a time when you remove the /nsr/index directory? Do you delete the client from NMC (and leave the /nsr/index directory there) or just disable it and remove it from all groups?
My personal preference on decommissioning clients is:
Note client ID
Delete client
Re-add client, preserving client ID, leaving it out of all groups
(Frees up license immediately)
For clients that are being pulled from DNS as well, I always maintain fake private subnets in 'hosts' on the backup server so I can keep the client name as something resolvable at all times. E.g., 10.x.y.z where 'x' and 'y' are guaranteably not in use. By doing all the above, the index stays on disk until it's clearly time to remove it.

What is your strategy for dealing with all the extra clients listed in NMC?
What is your definition of "clearly time to remove <the index>"?


Regarding the extra clients listed in NMC - I don't particularly see that as a major concern, though I'd typically recommend using a comment field for such clients starting with say, "Decommissioned" or "Decomm" if you want to be more economical. Thus, in any view they're readily identifiable.

My definition of "clearly time to remove <the index>" is at a point beyond that of the longest retention time. E.g., if a client was being backed up with a 10 year retention time, then the index would be kept for 10 years. Again, I see the cost of rebuilding indices/rescanning old media, etc, as exceeding that of a bit of extra disk space to maintain the indices on disk.

I'm obviously conservative in my approach, but it's the way I like to work with backup :-)

Cheers,

Preston.
