WebGISDR fails for Relational Data Store v11.3 - Create data store snapshot... "status":"failed"

[EstherSmith_Dev]

Hi all,

I am getting an error when running WebGISDR backup tool of  ArcGIS Enterprise v11.3 in full backup mode.. 

The Relational Store backup part fails instantly with error below.

Starting the backup for Relational ArcGIS Data Store:
Url: https://xyzxy.xyzxy.xyzxy.xyzx:2443/arcgis.

Failed to back up the Relational ArcGIS Data Store:
Url: https://xyzxy.xyzxy.xyzxy.xyzx:2443/arcgis.
{"jobId":"67xxxxxx-xyzx-xyzx-xyzx-xxxxxxaffd97","description":"Create data store snapshot 20250815-231920-58-FULL to \\\\xyzxyzxyzx\\xyzxy\\PROD-WebGISDR\\SharedLocation\\WebGISSite1755263959527\\dataStore\\35xxxxxx-xyzx-xyzx-xyzx-xxxxxxfa9349","lastModified":"2025-08-15 23:19","status":"failed"}

The backup of Relational ArcGIS Data Store has taken 00hr:00min:00sec.

The Relational Store validates successfully in ArcGIS Server Manager. The drive X where ArcGIS Data Store's temp is (X:\arcgisdatastore\temp) has three times free space than the current size of X:\arcgisdatastore folder. All looks ok as per https://enterprise.arcgis.com/en/portal/11.3/administer/windows/create-web-gis-backup.htm 

Data Store and ArcGIS Portal are in non-HA mode. Portal and Server back ups are completed successfully.  

Any clues why am I getting this error?

Thanks,

@EstherSmith_Dev ArcGIS Data Store backs itself up every 4 days.  Can you check the default location (i.e. C:\arcgisdatastore\backup\relational\dbbackup) and see if they are being created?

Are you actively using the backup modes "Full" and "Incremental"? Datastore requires PITR for full/incremental:

https://enterprise.arcgis.com/en/data-store/latest/install/windows/data-store-utility-reference.htm#...

If not using the incremental backups, I recommend using the "backup" mode as it's much simpler: 

https://enterprise.arcgis.com/en/portal/latest/administer/windows/overview-backup-restore-web-gis.ht...

Additionally, check the space on your C drive, the arcgis service account uses the %temp% variable as a swap space for this backup - lack of space here would prevent the backup entirely. Changing the variable location, to a disk with lots of space,  is recommended.
