Checklist for Backup and Recoverability Acceptance Criteria
Backup and recovery of data are default functionalities of large, complex systems. This is because, though systems are not expected to crash, in reality, a system crash is not uncommon.
The backup and recovery acceptance criteria specify the durability and recoverability levels of the software in each hardware platform.
The aim of the recovery acceptance test criteria is to outline the extent to which data can be recovered after a system crash.
Following questions must be answered in specifying the recoverability acceptance criteria:

1. | How much data can be recovered after a crash and how? | |
2. | Is the recovered data expected to be consistent? |
Generally, a system cannot recover from a crash unless the data have been previously backed up. The backup process includes taking periodic snapshots of a state of the system and saving them in stable storage to be retrieved later.
Following questions must be answered in specifying the backup acceptance criteria:
Sr. |
Check Point |
Yes/No |
1. | How frequently is the backup process initiated? | |
2. | How long does the backup process take? | |
3. | Is the backup expected to work on-line or off-line with normal operation suspended during backup? | |
4. | Does the backup process check if sufficient storage space is available to accommodate all the data? | |
5. | Is the backup process fully automated? |
