I am a SharePoint Administrator using SharePoint 2010 SP1 Enteprise Edition and I am running Powershell to backup nightly a FULL FARM backup.
Backup-SPFarm -Directory \\SERVERsqlbackup01\SQL_Full_Backups\SharePoint\spbackup\production-farm -BackupMethod full -Verbose
I also run backup's in SharePoint's Central Administration nightly to perform a full database crawl and then an incremental crawl every half hour on the SharePoint Farm.
My DBA is finding these backup's and they are causing him to wonder what is going on as I am NOT doing a differntial and he states that they happen only with simple database mode, not full.
IT IS ONLY HAPPENED ON SIMPLE MODEL DATABASES
This is an export from SQL Management Studio 2012 SP1 BI Edition

Here is concern,
The backup history for this SQL Server database indicates that backups are getting appended to existing backup devices. This increases the risk of losing all the backups when the backup device gets damaged. Also the performance of backup and restore operations
might be degraded when several backups are appended to one another on the same backup device that resides on a remote server and accessed over the network
Thank you!
Upon looking at this, this location, starting with "SERVERsqlbackup01" is using the backup's that SharePoint is creating and referencing that I am setting up in the PowerShell script. Why would SQL Management Studio be reading / referencing this / getting errors about this?
