Cannot create backups

Hi everyone,

I have Updraft (free version) + Vault Storage (paid) for 4 websites (WordPress). For 3 of them I can do the backups in 30-60 seconds, but for one of them it stops at the “Creating database backup (table: wpqy_postmeta)” step.

The Updaft is continuously trying to create this database backup and shows “next resumption” until it displays “next resumption 89 (after 24353454s).

I want to mention that this website is smaller than the other 3 websites which are backed up in 1 minute.

I’ve already cleared the database with Advanced Database Cleaner plugin.

I’ve configured the “Split archives every” from 400mb to 100mb, but this didn’t help.

The max_execution_time is 600.

The log can be seen at: https://pastebin.com/a0BSJ25P

Can anybody help me to solve this issue?

Thanks in advance!
