When trying to run a backup, the follow error appears:
Error: SQL command "select database_snapshot('backup_snapshot',false);" failed: ERROR 7804: LGE is lagging behind for 516540 seconds, it exceeds 3600 seconds threshold, LGE: 4859177, current epoch: 4936363
Backup FAILED.
Release : 3.7
Component : IM Reporting / Admin / Configuration
This error means that the database's last good epoch or LGE is significantly behind. This error can be overridden by utilizing the below entry in the backup's ini file:
SnapshotEpochLagFailureThreshold=$Value
The downside of overriding this can be noted when attempting to run the backup afterward:
WARNING 7814: Snapshotting at epoch 4859177. Current epoch is: 4936384, More recent data will not be included
