Issue/Introduction

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.

Environment

Release : 3.7

Component : IM Reporting / Admin / Configuration

Resolution

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
