Who Moved My Data? A Backup Tracking System for Dynamic Workstation Environments

Abstract
Periodic data backup is a system administration requirement that
has changed as wireless machines have altered the fundamental
structure of networks. These changes necessitate a complete rethinking
of modern network backup strategies. The approaches of the 1980's and
1990's are no longer sufficient and must be updated. In addition to
standard backup programs from vendors, specialized system
administration tools are often needed. This paper examines one backup
system and the major software components used to implement it. NCSA
has developed a Backup Tracking System (BTS)[Note
1] to perform backup operations based on knowledge of the network
and when each machine was last successfully backed up. BTS can
chronologically list all computers: from those currently attached to
the network through those that have ever been attached over the life
of the BTS program. BTS also provides information about all backup
operations including the time of last attempt, success state, amount
backed up, etc. The BTS database also contains the date of the last
successful backup for each machine and whether it has at least one VIP
user (to be given preferred status during backups) or all non-VIP
users.
