7 Homegrown Backup Scripts Many system administrators start with home grown backup scripts No initial budget for backup software and backup server Initially problem seems relatively easy for a Perl hacker Backup scripts don t scale Changing needs of the organization New platforms and applications New administrators Amanda uses similar formats as typical home-grown scripts Tar for Linux/UNIX Zip for Windows Script API: Allows for pre- and post- backup plug-ins Zmanda: Open Source Backup 7

8 Zen Innovations: Manual scripts to Amanda Our initial manual processes, scripts and cron jobs quickly started to get complicated as we grew our infrastructure. We needed to do backups regularly and be in a position to recover quickly without too much manual intervention. Our initial approach was neither scalable nor suitable to work efficiently.
