Title
Incremental Backup fails with error "Failed to build valid list of incremental entries" -
Description
Looking at binary log directly before failure warnings of “Failed to get status of file” can be seen. On examination of the warning internal message “Insufficient system resources exist to complete the requested service. (1450)” is seen.
Looking at the trace from the client “Unable to allocate 3825032 bytes of memory” is reported.
On checking available memory on the client it is observed that client only has 8GB memory installed.

Cause
Backup client does not have enough memory resources. Although this is not the minimum memory for a Windows 2012 R2 server as recommended by Microsoft this is not enough for a Windows file server.
-
Resolution
Increase memory on server to minimum of 16GB
