CLI script: Create protection groups for Disk based backups

  • Comments 2

The following script creates a protection group with disk based protection, for a simple folder. It can be easily extended to add more data sources of different kinds – like Microsoft Exchange, SQL, Sharepoint, System state or Virtual Servers. The Synchronization frequency and retention ranges etc. can be easily modified to suit your needs.  Also, since we are protecting a sub-folder in a volume, we are using the CalculateSize parameter in Get-DataSourceDiskAllocation, which would calculate the exact size needed for all the items in that folder. This is not needed when protecting an application like Exchange/SQL or protection the entire File system volume.

  • $dsname = "G:\"

    $poname = "G:\ProtectableFolder"

    Which field would change to create a exchange protection group?

  • Is there any way to include (by Auto Protect) ALL SQL DB`s onto a Server ? For example if you got 12 instances onto one SQL Server and you want them all to be included into the Backup procedure ? Thx in advance ?
