Replication risks

Replication is a two-way street and can quickly get confusing if you are allowing others to update or add to your backup set. Let's say you back up a folder and share it with Joe. It's possible for another user to download and synchronize a local copy of your shared folder. That means that changes the user makes to the files in their local copy of your shared folder are then replicated back up to the Mirra Sync server and then down to the original source copy on your desktop, overwriting it. If you both have the file open at the same time, whoever saves last will overwrite the changes made by the other.

Security is fairly limited. Remote users must use their e-mail address as their account names and can create passwords of their choosing. There is no enforcement of strong passwords, and you can make five attempts to guess a user's password. The system then locks you out for 10 minutes, and then you can try again.

For sensitive data, your best security is to password protect backups and not enable sharing of backup sets. Bear in mind, however, that passwords can't be retrieved if forgotten.
