Can’t complete backup

Hello there,

I used to backup my website with Updraft Plus and it worked perfectly, it helped me bring the website back after it was hacked. However, now I have problems and I don’t know how to solve them due to the lack of knowledge.

When I try to back it up manually, the process starts but then freezes with a message: “next resumption: 1 (after -1925s)” and nothing else happens no matter how long I wait.

Unfortunately I don’t understand anything in the Logs. I have regular backups scheduled and they appear in the list of Existing backups, however I doubt they are successful and don’t know how to check.
Besides, I have this warning: WordPress has a number (4) of scheduled tasks which are overdue. Unless this is a development site, this probably means that the scheduler in your WordPress install is not working.
I’ve read the article and made sure that the scheduler is enabled.
I also set Split archives every to 25MB but it didn’t make any difference.

All I want is to be able to backup my website at least manually. Any help will be appreciated.

P.S. Here is the link to the Log of the last “frozen” backup: https://we.tl/t-VeO63VRi5I
