Migration

The DTS copies and compresses data from on-line disk storage to off-line storage in order to maintain a sufficient amount of on-line disk space for ongoing processing. Customers can browse or edit their data after it is moved to off-line storage through a recall (automatic restoring) process: Off-line Disk Storage – Data that has not been used (e.g., browsed, edited) in the preceding 35 days are candidates for migration to off-line disk storage.
Off-line Tape Storage – Data residing on off-line disk storage for a period of 25 days is a candidate for migration to tape. Due to the time involved in a recall from tape, customers are notified when a recall is coming from tape and when it is complete.

Expiration
Data can be assigned an expiration date by the customer. Data having no expiration dates will be assigned a two year expiration date at the time it is migrated to off-line storage. Data is not accessible after its expiration date.
