Offsite Backup

For maximum data security, PBS offers the ability to replicate backups to remote locations via pull method. The secondary backup server actively pulls data from the primary server -- keeping control with the offsite system.

Thanks to client-side encryption, your data is protected even on untrusted target systems. The encryption keys never leave your local network.
