My mail server VM ran out of disk space today. Short investigation lead me to discover the backup_client.db file was 7.5GB. On my other servers, it’s under 100MB.
The mail is stored in maildir format (so millions of small files)… Is this going to create a huge database? Should it be that big?
Is there a command to “compress” or otherwise reduce that size?
Just coming back to this again… It’s grown to 15GB since I deleted it in January. I had it set to raw for every setting in the advanced tab, but noticed I missed the client side hashes in the internet tab. Changed it now, but I have doubts it’ll do anything.
Still confused how the hashes for ~10GB of files can take 15GB to store. It’s emails, so lots of small files, but surely the hashes are still smaller than even the headers of the emails.
Similar issue here. backup_client.db is 38GB, larger than the actual amount of data that I back up. Just changed hash settings, but if that’s going to be the fix I think I’ll have to just switch products.
