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.

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.
