![]() The shorter the time backed-up data is stored before it's needed for a recovery situation, the greater the cost of backup and storage. RPO values - usually a time frame such as seconds or minutes - are defined by business system and data owners and might be reviewed and approved by senior management. This is essential for disaster recovery, business continuity and information security.īackup policies should also include the recovery point objective (RPO) metric that defines how long data should be stored - e.g., aged - before it must be backed up again. These might specify that, in addition to nightly tape backups, point-in-time snapshots of data should be taken and replicated at frequent intervals during the business day to provide rapid, granular data and application recoverability. Critical business data might be further protected by policies that specify more dynamic backup activities. In this case, one set of tapes is kept on site to facilitate local recovery and a second, duplicated set is sent off site for storage in a secure location. The policy's default protection scheme ensures the recoverability of servers, network components and other infrastructure devices, as well as critical applications, databases and important files.įor example, a default backup policy for all application data might be a nightly backup to tape from Monday through Friday. This ensures that information from business applications such as Oracle, Microsoft SQL, email server databases and user files is copied to disk and/or tape to ensure data recoverability in the event of accidental data deletion, corrupted information or a system disruption. What is a backup policy?Ī backup policy sets forth the importance of data and system backups, defines the ground rules for planning, executing and validating backups and includes specific activities to ensure that critical data is backed up to secure storage media located in a secure location. The data backup policy template included below can assist in preparing the policy. The schedule, which should map to the backup policy, defines what should be backed up, types of backups to be performed, storage locations for backed-up data and other resources, frequency of backups, backup media to be used, time frames for executing backups, duration of backup storage, recovery of backed-up data and systems, and a means of confirming that backups were successful.Īssuming your IT organization doesn't have a formal, documented data backup policy, begin preparing one that is consistent with good practice, is compliant with relevant regulations and standards, and will pass audit scrutiny. Most likely a backup schedule is available that conforms to the overall backup process.
