How Data Migration Works Using UNIX and Linux Data Mover

Data migration is the process of moving data from a temporary storage location to final destination media in a staging-based backup job. In other words, Arcserve Backup migrates the data residing on staging devices, such as file system devices (FSDs), physical libraries, and virtual tape libraries (VTL), to final destination media after the Copy policy defined for the jobs are fulfilled. The final destination media can be tape media or an FSD.

Using UNIX and Linux Data Mover, Arcserve Backup lets you migrate data using the scenarios described in the following table:

The above migration jobs can be submitted via the primary server or the data mover server. Migration jobs execute from the primary server or the data mover server based on the method used to specify the final destination media.

Example: Server that Executes Migration Jobs

The examples that follow describe the server that executes migration jobs.

• Primary server--The following screen indicates that the user selected the final destination media from the media associated with the primary server. The migration job executes from the primary server and utilizes the primary server's system resources.

  

• Data mover server--The following screen indicates that the user selected the final destination media from the media associated with the data mover server. The migration job executes from the data mover server and utilizes the data mover server's system resources.
