We currently do backups to tape for our network.  I also use a Veritas Replicator to replicate some databases to our Disaster Recovery site.  We would like to move away from tape, but I need some ideas and suggestions on what other people are doing.  We will also some some backups encrypted for this new Mass Privacy law that comes into affect March 1st, 2010.  Thanks!

    Depending on the amount of data you are backing up the two viable options I would reccomend would be backup to tape or possibly an offsite backup solution like iron mountain online backup.

    Both of these have pros and cons and it depends on your organization and budget which will be best for you. Large amounts of data make it extremely expensive to use online data protection as they usually charge by the GB and it can get quite costly.

    If you do a backup to disk solution you will definitely want one that does compression and deduplication so you get the most bang for you buck.

    You mention you have a disaster recovery site, if you have the budget you may want to take a look into the EMC avamar solution. This has an incredibly high rate of deduplication and very fast backup/recovery speeds. The only downside is you would need to purchase two of them to replicate your data between your real site and your DR site.

    At this point, $$ isn't necessarily an issue.  What online solutions are people currently using?  I'll check-out EMC avamar as well.  I've seen some backup to disk to 'the cloud' solutions, but looking for what others are actually using.  thanks.

    If money isnt an object I would seriously take a look at the EMC avamar. We did a proof of concept of their solution and it was impressive. Depending on your data and amount of change you can see anywhere from 20x to 50x dedup. They have a tool that you can run on your servers for a few days that analyzes your data and tells you what you can expect from their product.

    In the end however the cost was too high for our company.

    We eneded up going with an EMC dl3d backup to disk solution which has worked very well for us.

    I work in an education environment with 2000+ users and we have the following setup:

    User data backed up daily to tape (LTO 3) by incremental backup - 2 x tapesets alternated daily (overwritten after 1 year)

    Database backups ran hourly (incremental) to backup drives in servers. This is backed up to tape as a full backup every day - 2 x tapesets alternated daily (overwritten every other day)

    System State server backups spread over the week - stored on storage server.

    Full backup of user data, databases, and system state backups done over the weekend - 2 x tapesets alternated weekly.

    Tapes stored in separate building in a fire resistant safe.
    We have an offsite storage agreement with another establishment where we store the previous full backup.

    I hear you on the back-up tapes...  I'm trying to move away from them.  That's what we are currently doing, and MAY end up being our best solution.  Sounds like a lot of us are doing it that way.  Anybody doing it another way?  Thanks!

    NAS/SAN are the main other, but even then offsite's are still to tape :) There are those who offer on-line backup services that will send your files to their facilities, but I doubt that would scale for a large data set unless you had enough pipe.
    We have two DC's and a large pipe between the two, and we have the data sync'd between the two, both doing backups to SAN and weekly's to tape to go offsite.
