Data backup

By dennis.g.cogan ·
Amount of data that needs to be protected continues to grow. No one knows the words "purge" or "delete" anymore.

I am always challenged by my management as to whether or not there is a better way to backup close to 100 TB than using tape.

We currently have (2) tape libraries, each with 8 LTO3 tape drives. Looking to expand. We support Windows, HP-UX, VMS, Tru64 Unix, Solaris, and Linux.

Anyone have any ideas other than tape, or disk-to-disk-to-tape. Need to make sure the data is safe and secure. Need to make sure a copy gets off-site.

Would appreciate your thoughts.

Depends on what better means

by NotSoChiGuy In reply to Data backup

Better could mean more reliable (failure rates on tapes seem to vary widely depending on what study you read), or cheaper (reduce costs on tape, equipment, shipping, storage, etc), or some combination thereof.

You could do something along the lines of eVault, if you've got the bandwidth. You could go with a mirrored warm site with a firm like Sunguard, if money wasn't a hindrance.

I suppose the best pieces of advice I could offer would be to encourage you to determine (if it hasn't been already) what exactly your firm needs with regards to data protection. Form follows function is particularly true in the area of DR/BC planning. After you have the requirements firmly squared away, start researching different vendors from different market silos that speak to your needs. Get some rough estimates together, compile what you currently spend, and discuss it with your management. You'll end up determining your risk appetite vs. your cost appetite, and things should shake from there quicker than you'd imagine.
