[Dovecot] Not backing up cache files
I am using mdbox for dovecot storage.
I wonder if I could skip "dovecot.index.cache" files and, in general, "*.cache" files when doing mail backup. Those files are big and change frequently. What I feel from reading documentation [1][2] is that they could be dropped in the backups, to be recreated on the fly if needed.
But I would like expert confirmation.

Thanks!.

i'm not the expert you're looking for, so dont take my word as one. And i'm basically using Maildir instead of mdbox ...
Anyway, i have dropped 'dovecot.index*' from some backups, full and incremental ones, action which made me save some Gbs of space on them. I already restored some accounts from these backups and had absolutely no problem at all !

Both of the responses to your question apparently missed that you are using mdbox.
Obviously you can NOT ignore/delete the index files for dbox storage formats, but I'm not sure about the cache files.
I *think* you can ignore them, but I'd have to defer to someone else for a definitive answer, and I'm definitely interested in the answer to this too since I'm considering migrating to mdbox myself.

I stopped "dovecot".
I did a ZFS snapshot (play safe!), and disabled incoming messages.
I deleted ALL "dovecot.index.cache" (one per mailbox, I have about 500 mailboxes) without any apparent effect.
I started dovecot.
I moved around with apparently no side-effects. Cache are recreated, small size, growing as you download messages.
I still would love an authoritative answer.
