Hi,
Apologies for the delay in replying.
From the log, it appears that your uploads folder is very large (approx. 18GB). This is why the backups are taking up a lot of resources.
In order to help reduce the size of the backups, the following folders should be added to the Uploads backup exclusion list:
- wc-logs
- wp-migrate-db
- wpfc-backup
You may also know of some other folders in the uploads directory which does not need to be included in the backup.
Regarding the files left in the updraft plus directory, these appear to be temporary ‘.tmp’ files, and should be automatically cleaned up by the server within 24 hours.
If not, there is possibly an issue with the server’s cleanup, which your hosts will need to look into.
