I took a copy last night and I restored it to the other server so I could test upgrading the databases. If it works, we will have to do it for real which require taking the site offline for at least 6-8.

It takes a long time to do a backup because the attachment table is now 46GB. A Mysqldump is single threaded, so I had to use a tool to thread it and get it down to 2-3 hours. But that is 2-3 hours to backup and 2-3 to restore and the site must be offline during.

I’m not finished testing the new db, but in the meantime there may be intermittent slowness."

So that is where we are...thanks for everyone's patience.
veam backups

attachment table

Mysqldump is single threaded

I know the feeling. Sometimes when I back up from the table and go take a sqldump, it can take a while.
