I just recently installed UTS 6.1.3 and it's been working fine, but I just noticed today that it stopped backing up. The last backup was on Feb. 8th.
When I check the log, this is the error it shows:
"extensis.esp.admin 115 datastore operation failed: IOException while creating backup file "/Applications/Extensis/Universal Type Server/data/backups/2017_02_14T19_38_57_015Z.tar".; nested exception is:
extensis.esp.exception.DatastoreOperationFailedException: File length (2147491840) exceeds maximum length of a tar entry (2147483647)"
When I try to manually run a backup, I get the same error.
It's running on a Mac Mini with macOS Sierra, almost 500GB of available space, and no other third party software.
Any idea what could be causing this all of a sudden?
