ACKUP
When you perform network backups in a nonteamed environment, overall throughput on a backup server adapter can be
easily impacted due to excessive traffic and adapter overloading. Depending on the number of backup servers, data
streams, and tape drive speed, backup traffic can easily consume a high percentage of the network link bandwidth, thus
impacting production data and tape backup performance. Network backups usually consist of a dedicated backup server
running with tape backup software such as NetBackup, Galaxy or Backup Exec. Attached to the backup server is either a
direct SCSI tape backup unit or a tape library connected through a fiber channel storage area network (SAN). Systems that
are backed up over the network are typically called clients or remote servers and usually have a tape backup software agent
installed.
