Backup FAQs & Additional Information
More information about the service:
Here an overview of the current hardware used in our Commvault system.
Backup data from your servers is sent to a dedicated backup location on campus. Once backups have completed, the data is then replicated to other data centres around campus. Your data is available for recovery from any of these locations.
Our data centres are:
We can perform backups over the standard campus network. If required, a dedicated backup VLAN is avalible in ITS data centres.
Our dedicated backup location has 40Gbit connectivity to the campus network, each Commvault server has multiple 10Gbit connections to its local network.
HP DL380p Servers
'Media agent' servers receive and process backup data from clients. Five of these are located in remote data centres to manage the secondary copies.
Nine storage arrays (5.5PB usable) located across the campus data centres.
Backups are retained depending on the service you choose, however the retention concept remains the same.
Here is an example of the restore points, for a server on the 'Standard Backup' product.
› 14 Daily Backups
› 4 End-of-week backups
› 12 End-of-month backups
› 2 End-of-year backups
This example assumes today is the 2nd of April. The Green highlighted days show the restore points available if a request to restore data was recieved on the 2nd of April.
As you go back further in time, the restore points get further apart. Files can only be restored if they existed at the time the backup was made. For example, If you created a file on 21 Dec and deleted it on the 24th Dec in the previous year, it would not be available for recovery.
There are several options available to manage the risk of data loss. Here are are some valid options, priced per TB per year.
