The database is backed up several times each week, as indicated in the table below. Several database maintenance scripts are run after each backup. Batch experiments that are loading when a backup begins are restarted when the backup and maintenance scripts are completed. It is not necessary to resubmit these experiments.
|Monday||12 AM EST||"Hot" database backup. Data submitted for loading will be entered into a queue, to be processed and loaded into the database only after completion of the backup (about 4-5 hours).|
|Saturday||01 AM EST||"Cold" database backup. Database unavailable for 5 hours.|
