I am looking for a solution for moving around 3TB offsite? any ideas? Tapes take too long to backup, and offsite solutions would cost in the range of around 1000$ per month. Are hardrives a solution? Any idea's even ones I have shot down would be appreciated. Thank you.

" full situation "

Full situation, We currently have 7 servers creating around 3TB. We would like to have weekly backups but if the place went up in flames we would have around 1 week or so to get back up on our feet. We need around 1 month to go back 2 would be nice. Currently we are able to do backups of every server nightly except one which is our File Server generating 1.9TB alone, which we backup once a week on weekends. We want to have all our data offsite in case of a disaster. Recovery shouldn't take more than the 1 week period of time.

We dont need to move offsite daily. We have daily backups to a Server We have an issue moving offsite.
