Access to a secondary copy of the data
Different data resilience technologies have different restrictions to the backup data set. Access to the backup data set requirements indicates the level of access that is required to secondary copies of the data for other work activity off-loaded from primary copies, such as saves and queries/reports. You should consider the frequency, duration, and what type of access is needed for the backup copy of the data.
Possible requirements can be:
- None
- During non-production periods
- Infrequent but during normal production for short (seconds to minutes) durations
- Infrequent but during normal production for long durations
- Frequently during production for short durations
- Frequently during production for long durations
- Nearly all the time (near continuous)
