Issue/Introduction

Is DISK BACKUP and RESTORE affected by DAYLIGHT SAVINGS TIME (DST)?

Environment

 Release: Disk™ Backup and Restore.

 

Resolution

During Fall Daylight Savings time Disk would be affected, if backup/archive is run in the hour after the fall back. Disk could create an entry for the new backup with an ‘older time”.    As long as the database/data set is not reorganized, the versions will be okay. It is recommended not to run backup/archive during that hour. 

During Spring Daylight Savings time Disk is not affected because the time isn't replicated.
