Lets say I have a 50gb single file.

Lets also say it's database file. (or any easily modified and frequently updated file)

I'm wanting to back this file up over the internet for offsite storage purposes, as opposed to anything onsite.


What are my options?

Is there software than can look at a file and tell which physical sectors have been modified and backup only those sectors? I'm looking for something to that effect, instead of transferring that much data every day over the web.

Is this making any sense?

just make tape backups daily and store them offsite

Things like Netbackup and Backup Exec will look at the archive bit, and see if the file has been modified, and only backup the modified file. In your situation, sounds like that will be every backup cycle. There are plug-ins for those products that will fix that problem, and let you backup your database via a script, if its supported, and if you want to pay for it.

Another product is the Avamar Axion. That breaks files down into pieices and backs up the pieces, which may allow you to save some time and space. Setting up an Axion in your back yard isn't at all feasable, and would cost more than you are likely looking to spend. There are companies that basically setup Axions, then will sell you space on that Axion, and you will backup, over the Internet, to that Axion, for a fee. Try Fastservers, or Time Warner Cable, or Verio, I know they all offer the product.

I'm not sure how Connected deals with things like this. Its basically another disk-based solution like Avamar Axion. I don't know if Connected has "commonality" or not. It might, Google could help. Iron Mountain is now offering a re-packaged service using Connected, not sure the price.

AT&T, Bellsouth, and Verio all have a "home consumer and small business" option for using Avamar Axion. Not sure if they would have a package to suit your needs.

Finally, Symantec has a new consumer product out. I am not sure what its back-end is, I would wager Connected or Avamar. Might try that. They WERE offering a free trial.

Not possible to have the DB program write redundant files? That way, you can have one go down for 15 min (or whatever it takes to transfer it) and then sync up with the new one once you are done.
