We have a NAS (HP Media Vault 2120) in a small office with 5 WinXP machines that save files onto one of the directories in the Media Vault. The vault is basically a centralized hard disk.
A couple of times people have deleted files in the Media Vault and we're looking for a way to be able to recover files, at least within a few hours or days of deleting them.
I'm looking for a solution that doesn't involve too much time. I'm OK buying something.
Alternatively, if there's a way to set it up so that only some users can delete files but everyone can add/update them.
I'm spoiled. I used Dropbox on my personal machine and this would solve the problem. The issue is that we cannot save data outside the office.
