AMASS Overview
Automated Backups Because the File System Database is extremely important, this
via Cron Job information must be protected. Consequently, the amassbackup command, run from a cron job, regularly backs up both the Database and the Journal. The Journal is a transaction log of daily activity. This cron job is created when AMASS is installed. The cron job backs up the Database and Journal to a Backup Volume at 3 a.m. using the following schedule:
•First day of the
•All other
After the backup completes, AMASS truncates the Journal file.
If the above schedule is not suitable for your site, modify the schedule by editing the crontab and changing the amassbackup entries. For detailed information on making a Backup Volume and editing the cron job, refer to Managing the AMASS File System.
Caution
Make sure these backups are successful. Look in the system log every day for a “Backup was successful” message.
The full backup (backs up the Database and Journal) and the partial backups (backs up just the Journal) will allow you to successfully restore your File System Database (and, therefore, allow you to know where data is located on what piece of media) if your current File System Database gets corrupted or the hard disk crashes.
