Backup via SMB or NFS
A SnapScale cluster can be backed up via standard file server access.
In this configuration, the backup server is set up to use SMB or NFS to connect to the cluster,
examine the file system, and then back up the data onto itself. No special agents or media
servers are needed.
Off-the-Shelf Backup Solutions
Special Application Notes for installing the backup agent or media servers can be found on the
Overland SnapScale Support website (
http://docs.overlandstorage.com/snapscale
NOTE: The backup packages shown in the Application Notes do not support the backup of Windows
ACLs. If Windows ACL backup is critical, Overland Storage strongly recommends you create a
disaster recovery image before you perform a backup.
A SnapScale can be backed up using a third-party Linux agent or media server installed on
one cluster node. A tape drive or library can be attached to the node to provide local backup of
the cluster.
Utility IP Address
To provide continuous access to a specific cluster node with a backup agent or media server
installed even when a public IP address changes, a special Utility IP address can be assigned
that operates in addition to other cluster-assigned IP addresses and is always associated with
the specific node. Then, if the public IP address of that node changes, backups continue to
function without the need for the administrator to take action.
This IP address setting works for both the node as a backup source (backup from the node to
the backup server) and the node as a backup target (backup from any machine including the
node to an attached tape drive).
