Setup a simple backup job

Mach03 asked
Hi Experts,
I just acquired a new client that has Simpana Commvault express and I'm use to Backup Exec, so this software package is a little backwards to me.  What I want to do is do a full backup of a single server every night with the same tape.  

To do this in BE, I would first create a media set (special server), set it to 22 hrs of overwrite and append protection, then associate media #44 to it.  Then I would create the job "special server backup", associate it with "special server" media set and schedule it to run every night.  

How can I accomplish this in Commvault?

in commvaul tu can drive it using storage policies and backup policies.

have the backup configured to backup to disk. then setup a aux copy to backup the primacry (from disk) to tape, and can leave the tape in library until full .
Out of curiosity, what is the reasoning behind using a single tape for a single client?

You could get somewhat similar functionality, however, there isn't any hour based granularity within Simpana, so you would have to adjust your method a little. The simplest work around would be to use 2 tapes instead of 1, and setup the job so that it alternates between tapes.

To do this, you'd need to have a look at doing the following (very rough steps):

Create a new Spare Media Pool, for use by the two tapes,

Create a Barcode Pattern (Simpana Control Panel, Media Management), to associate the two tapes to the specific Spare Media Pool. (Once the Barcode Pattern is created, you will need to associate it to the newly created Spare Media Pool)

Create a new Storage Policy specifically for the client. This Storage Policy would need to be pointed to the Tape Library, (using the new Scratch Pool). You would also need to configure retention to something like 1 Day, 1 Cycle.

Create a Schedule Policy for the nightly full backup, and enable the Advanced Media Option: "Mark Media Full on Success".

The result would roughly be:

Night 1, Tape 1 is written to,
Night 2, Tape 2 is written to, upon succesful completion of the Full Backup, the Data on Tape 1 is marked for Aging,
Night 3, Tape 1 is written to, upon succesful completion of the Full Backup, the Data on Tape 2 is marked for Aging,
And so on...

If you were simply writing to Disk instead of tape, this would be much simpler.

How have you gone with this?
