hey guys,
All clients are v2 indexing at this point. I get an alert every so often that index backups haven’t ran in 30d for NDMP client. Each and every day there’s 100GB of inc. data being backed up, but the system scheduled Big Data Apps Index backups for that SP show that only “full” backups ever pick anything up, each day of the week when the incs run for the subclients of that NAS client, there doesn’t seem to be anything backed up at the index server level. Of course you can’t see any of this in the Command Center but is it normal for the classicIndexInstance backups to be zero bytes (and thus immediately age) in between Fulls?
I see this phenomenon even on very small, minimal churn non-NDMP clients, so my question is - is there some threshold which determines IF an index server backup has anything new to write? For my very large-ish VMware SP’s and their Big Data Apps Index backup - those scoop up stuff every day, there’s never a 0 byte index backup, then again the SP has 3300 VMs associated. So there must be some algorithm or minimum delta index change which determines whether it does anything or not??
I don’t see anything in the BoL for this nor anyone else seemingly asking this (or the search failed me).
thanks
