View Full Version : Best use of backup sets

August 4th, 2009, 05:55 AM
I'm debating the best way to use backup sets.

I have about 20 servers that I am backing up for a total of about 20Gb. of data.

I have 2 Tb of media (disks) to back up to.

I have one backup server dedicated to receiving the backups and moving them to the storage media.

I can easily create 5-6 backup sets distributing them in logical categories by products and type of servers. ex. product 1 web servers. product 1 DBs, product 2 web servers and so on.

But I am thinking making sure the runs do not overlap and so on will mean having to keep track of things a little more.

Would it be easier to have only one backup set?

Are their benefits to having more than one set?

From your description, it appears that you are backing up to disks. Amanda writes to the media sequentially from the holding disk. If you divide the data into multiple backup sets, you can perform the backup jobs in parallel from holding disks to the storage media.
If you divide the data into multiple DLEs, you can backup each DLE in parallel from the client to holding disk (assuming there is sufficient network bandwidth between server and

If you have multiple backup sets, you can do restores also in parallel.
