Couldn’t find anything in a web search for this exact error, so before I create a support ticket, I wanted to get forum moderator eyes on this.
Background: we take weekly synthetic fulls of our daily incremental jobs. Then at the beginning of each month, we look back 2 months ago, and age out any synthetic fulls that are not the last one of that that month. This way, we should have a single end-of-month synthetic full backup for each month, starting 2 months ago and going 12 months, after that point we age out and expire the oldest synth fulls.
Problem: a user asked me for a folder from 11 months ago. No problem, I think - that’s what our old synth fulls are for.
We’re using the Windows File Agent, so I “show backup history” on the subclient, scroll down to the bottom of the list, right click the synthetic full for June 26, 2021, and hit “browse and restore”
I immediately get an error in the browser: “No items found in the index, possibly index is being rebuilt. Please try later”
I then tested all my newer synthetic fulls. As it turns out, every synth full until 1/26/2022 gives me the same error. I.E. Jan 26’s synth full can be browsed without an issue. But the next-oldest one, December 25th, gives me this error and all other older ones do too.
As far as I can tell on my main mediaagent, the index is NOT being rebuilt.
This is very worrying. I trust commvault to hold onto my backups for 12 months, exactly as I specify. Why am I getting this error about an index, and what can I do to resolve this and get my user’s folder back?
Note: I have another subclient backing up a different drive on the same client. Exact same retention settings. These old synthetic fulls DO seem to be working (i.e. I can browse them). So it’s just this one subclient.
But I need the subclient in question working. I don’t like having to guess whether or not my backups are working.
