Hello,

Amazon S3 Backup was working fine till last week, But for this week backup fail with the below error #

Error:
Unable to create the remote backup: Transport error: Extension transport: ext://s3-backup/server/: Part number must be an integer between 1 and 10000, inclusive

Please, help me fix this issue.

Kind Regards

This happens when the backup file is too big, which causes the S3 part number to exceed the 10 000 part limit.

I don't have a solution other than shrinking the backup file. Maybe exclude some files/directories (cache, UpdraftPlus back-ups, etc.) from the backup? Or use a different compression level in the backup settings.
