Avamar backup failing

Good afternoon all. Running into an issue that has been occurring for awhile. Doing a file level backup on a sql backup. Windows Server 2003.

The backup errors out with insufficient resources. Any suggestions would be appreciated.

AVS client is installed on the D: drive with 57.7GB free.

SQL backups are on the I: drive with 275GB free.
