How to implement snapshots
(RPOs) by supporting more frequent recovery points. When properly implemented, snapshot data can be used to restore lost files or recover from more substantial data loss. Features like data deduplication are also appearing in snapshots to reduce disk storage requirements, allowing for many more snapshots and longer retention periods. Below are a series...

more frequently. Disk offers far better performance than tape systems, allowing for faster data transfers as well as greater long-term reliability. Disk can accept complete backup volumes, as well as simple file copies. For example, backup software can send a full backup volume to a virtual tape library (VTL) emulating the behaviors of a traditional tape system...

What is the difference between server-free and LAN-free backup?
is simply connecting the server that needs to be backed up to a SAN, so the data is transferred over Fibre Channel to a tape drive, VTL or disk.
In server-free backup, the data does not flow through the server being backed up. The server being backed up is still involved, because it has to do things like quiesce the... More... |
