Optimizing Multi Storage Parallel Backup for Real Time Database Systems
Real time databases are processing millions and billions of records on daily basis. Processing and taking backups of those real time databases are highly expensive. Traditional backup methods are progressively more difficult to back up huge volume of data’s. To overcome this issue, in previous work we addressed the difficulties of the issues and provided a solution for compressing the real time...
متن کاملOptimal Backup Interval for a Database System with Full and Periodic Incremental Backup
This paper considers the following backup scheme for a database system: a database is updated at a nonhomogeneous Poisson process and an amount of updated files accumulates additively. To ensure the safety of data, full backup are performed at time NT=L or when the database fails, whichever occurs first, and between them, incremental backups are made at periodic times iT (i=1, 2, ..., N-1) so a...

متن کاملBeyond backup toward storage management
The IBM Tivoli Storage Manager, a client/server product providing backup, archive, and space management functions in heterogeneous distributed environments, performs extensive storage management after client data have reached the server. Beyond minimizing the amount of data that a client needs to send on successive backup operations, Tivoli Storage Manager optimizes data placement for disaster ...
متن کاملExploiting A History Database for Backup
Database systems provide media recovery by talcing periodic backups and applying a recovery log to a backup to r’estore the failed media. A transaction-time database is one that retains multiple versions of data, recording with each version the time of the transaction that created it. Such a database provides access to historical versions based on transaction time, and permits reconstruction of...
