Microsoft Database Applications and Multiple Backup Sources
Microsoft produces three database applications: SQL Server, Exchange, and SharePoint. Any given database within any of these database applications should only be backed up by one backup source. It is not recommended to back up the same database with multiple backup sources, unless all of the backup sources use full backups only. There is a great risk of backup failure and/or data loss if a database is backed up by multiple backup sources and incremental/differential backups are involved.

You can control how many old backup cycles to keep.

Finding Large Files via PowerShell
File System backups with Carbonite Safe Server Backup (CSSB) are “file level.” If a file changes, the entire file is backed up next time CSSB performs a backup that includes that file. As a result, Incremental and/or Differential backups can be larger than expected. These instructions can help you determine which large files change.
