How Archive to Disk to Tape Works

Archive to disk to tape is a method of protecting data that lets you archive data to a temporary data storage location (staging area), and then based on selected policy options, migrate (copy) the data to the final destination (which could be a tape or disk), or automatically purge the data from the staging area after a specified duration time. When necessary, Arcserve Backup lets you restore data directly from the staging area.

Archive to disk to tape is a two-part archive process.

• Archive Process--Arcserve Backup archives data from the source to the staging location. The staging location is a Disk Staging Device.
• Copy Process--Arcserve Backup copies or migrates the archive data from the staging location to the final destination media. The final destination is usually tape media, but can be another Disk Staging Device.

Note: Arcserve Backup lets you transmit up to 32 streams of data using multistreaming. To archive data using multiple streams and transmit more than two streams of archive data, you must license the Arcserve Backup Enterprise Module.
