Prevent Dump Files from Being Overwritten

The tape retention in days configuration parameter specifies the number of days that must elapse between the creation of a tape file and when you can overwrite it with another dump.

tape retention in days applies to all dumps requested from a single SAP ASE.

Use the retaindays= number_days option to override the tape retention in days parameter for a single database or transaction log dump. The number of days must be a positive integer, or zero if the tape can be overwritten immediately.

Note: tape retention in days and retaindays are meaningful only for disk, 1/4-inch cartridge, and single-file media. On multifile media, Backup Server checks only the expiration date of the first file.
