Good info. Thanks. A couple follow-up questions:
We have 4 CI servers. As a R/W server reaches 30 million objects, we have to migrate that off to a Read-Only VM. We have 3 R/O servers, and one main R/W server. For a total of about 10TB of CI data. Does a backup of this count against the capacity licensing? I assume it does.
Going by the instructions in the link you provided to backup the search index; If I, while on the sub-client/content tab, browse to the instructed location, it looks empty.
Any ideas? Just create a support case?
