RE: [ActiveDir] Backup Strategy

[Rodriguez, Daniel [EPM/SRM]]

I am kinda in the same boat as you.

 

I have talked to my management and they seem please with the recommendations that I have shown them.

 

Now what I have: I have two DLT-IV Tape Libraries that are backing up a combined total of 200Gb a night. I am looking at the Compaq Itanium Disk Array with LSO Tape Backup. I am using Backup Exec 9.1 and will utilize their Disk-to-Disk Backup at night, and then during the day, backup to LSO Tape so I can monitor it. Also, the disk array will allow me to move the data off some of our servers for disaster recovery.

The money that you invest in you scenario, you can purchase a good tape library, disk array. IMHO.

Subject: [ActiveDir] Backup Strategy

I am sorry if this is off-topic, but I greatly respect the opinions/suggestions that come from this list.

I am working on a backup strategy for my company. We have just over 300GB of data to back up. I have been asked to estimate storage capacity/cost required to keep data for 1 month and 3 months, so this means that we will need between 1 and 3 TB of storage. The current backups are stored on a SCSI array and the plan is to use USB drives for offsiting our data. This means that we will need 4-12 300GB USB drives to store our offsite data.

 

I personally do not like this solution and am in favor of a disk/tape solution; using a disk array for onsite backups and using tape for offsite backups. The company prefers disk-based backup because of its speed. However, I think that disks are less reliable than tape and that using USB drives is not an enterprise-class solution (I have also heard that those 300GB USB drives are not too reliable). Not to mention the fact that these drives are bulky and our server room is already pretty cramped.

 

Does anyone have any suggestions? Are my concerns valid? Is my suggestion of disk/tape the best solution?
