Re: [Veritas-bu] How to add 125TB of data to the backup environment

If you do replicate the data offsite, what are the costs associated with bandwidth, disk storage, and maintaining the other site? Also, you might want to consider de-duplication for multiple copies. If you are running just off the replication, and your database goes corrupt you are up the creek. If you don't need replication I can't really see 125TB of high-end storage being less expensive than a library and media. If you can't break this amount of data down you might consider monthly or even quarterly fulls and weekly differentials / cumulative backups.

Sounds like a challenge any way you slice it. :)

Subject: [Veritas-bu] How to add 125TB of data to the backup environment

Hey Guys I am fighting with management on the cost and best method to back up 125TB of new data in my environment. I am running Netbackup 6.5 in a windows environment with 4 media servers. I am currently backing up 53TB mostly to disk first then using an old L180 with 10 SDLT220 drives to duplicate and send the data offsite.

I have a request from other departments that we need to back up an additional 125TB of data and send the data offsite. I proposed a new tape library but management wants to know if this data can be replicated or is there some other way to get this data offsite that may be cheaper than the cost of a SL8500 Tape Library in the low $300K range. So I am interested in hearing from Administrators who are responsible for large environments etc. What method are you using to store your data offsite?

Thanks
