V-79-57344-3849: ​​​​​​​0xe0000f09 - An error has occurred when writing to the Backup Exec Database. The data from this job's backup source will not be saved until the next full or incremental backup is performed

Problem

VMware/Hyper V Full or Differential backup fails with error "0xe0000f09 - An error has occurred when writing to the Backup Exec Database. The data from this job's backup source will not be saved until the next full or incremental backup is performed".

Error Message

This Error is seen in Backup Exec 20.6 and 21.

Solution

The error is seen in the following Scenario 1,2,3,4. Fix is for 1 and 2. Scenario 3 and 4 are working as designed.

A private binary is available for (BE 20.6) Scenario 1 and 2. It can be obtained by contacting Technical Support.
A public fix is available for the error received for Scenario 1 and 2 in BE 21.1
It is recommended to upgrade to BE 21.1 inorder to fix this error.

NOTE - Scenario 3 and 4 are normal behavior of the product where, if a full expires (due to less retention) then next incremental would run as full.

Scenario 1 -

Full backup of Hyper V/VMware ran on Day 1
While the next Full backup was running, the Day 1 full backup expired.
This error will be seen for the full backup of Day2

Expected Behavior - Full should not fail if earlier full is deleted or expired

Scenario 2 -

Full Backup of HyperV/VMWare was run on Day 1.
Diff 1 backup was run the next day.
When Diff2 backup was running, Diff1 expired and got deleted. Then Diff2 fails with this error.

Expected Behavior - Diff2 should not fail of earlier Diff1 is expired/deleted. The latest Diff would depend
on Full set so intermediate Diff should not cause the subsequent Diff to fail.

Scenario 3 - 

Full Backup of Hyper V/VMWare was run
Incremental backups 1 - 2 - 3  were run as normal
When Incremental 4 was running , the full expired/deleted then this backup would fail and next Incremental should run as full. This is normal behavior.

Scenario 4 -

Full Backup of HyperV/VMware was run
Incremental Backup  1 - 2 - 3 were run as usual
Full expired before Incremental 4 was to start, then Increment 4 would run as full.
This is normal behavior.
