Hello --
We are running SQL Server 2008 R2 64-bit on a Windows 2012 R2 Standard 64-bit system. Our backup plan utilizes the MaintenanceSolutions.sql scripts. The Database Backup = USER_DATABASES - FULL job involves twenty databases of sizes ranging from twenty megabytes
to over 300 gigabytes.
Two of the largest databases were recently reconfigured to utilize a separate FILESTREAM volume from the others due to space limitations of the original volume. Both were interactively backed up to a temporary folder on another volume. The databases were
then deleted, and subsequently restored with the new FILESTREAM volume configured in their options. The databases were successfully accessed by our users after the reconfiguration of each had been complete.
The larger of the two databases, which is 360 gigabytes, completes backing up in about three hours. However the other database, which is 326 gigabytes, is taking a day and a half to complete. I compared the properties of the two databases, and I did not see anything different in their configurations.
The DatabaseIntegrityCheck -USER_DATABASES and IndexOptimize - USER_DATABASES job histories did not list any problems. The backups of all the other databases are not taking nearly as long to complete.
I am going to be interactively backing up the problematic database this evening to see if the issue is within the backup job, or the database itself. Beyond that, what other steps can I take to troubleshoot and correct this issue?
