Incremental Backup

Incremental Backup

What It Is

Incremental Backup builds on and enhances the current backup capability by letting you perform backups faster and use less storage by allowing you to only backup the changes since the previous incremental or full backup. With MarkLogic 8 you can have multiple daily incremental backups with only a minimal impact on database performance.


Incremental Backup

Why It Matters

More frequent backups means a smaller backup window, which reduces the consumption of CPU and Storage I/O, enabling the infrastructure to be available for other workloads sooner.

Incremental Backup also reduces the Recovery Point Objective of the database in case of disaster. Log Archiving, an existing feature, works in conjunction with backups to enable fine-grained point-in-time recovery. However, archives of logs take up quite a bit of storage. Now, with incremental backup, logs can automatically be purged in conjunction with incremental backups allowing for point-in-time recovery at a much lower cost. For example, when using daily incremental backups in conjunction with 24-hour log archive retention, a restore can be made to any point in the previous 24 hours.
