tape retention in days specifies the number of days you intend to retain each tape after it has been used for either a database or a transaction log dump. This parameter can keep you from accidentally overwriting a dump tape.

For example, if you have set tape retention in days to 7 days, and you attempt to use the tape before 7 days have elapsed since the last time you dumped to that tape, Backup Server issues a warning message.
You can override the warning using the with init option when executing the dump command. Doing this causes the tape to be overwritten and all data on the tape to be lost.
Both the dump database and dump transaction commands provide a retaindays option, which overrides the tape retention in days value for a particular dump. See System Administration Guide: Volume 2 > Backing Upa and Restoring User Databases.
