About object change tracking
NetBackup 11.1 introduces Object change tracking, a feature that leverages object storage vendors' native mechanisms to identify the changed objects. S3 Bucket Logging is one such feature that tracks operations such as create, update, and delete. NetBackup analyzes these logs to efficiently identify changes and perform efficient incremental backups.
Compared to traditional object scanning, object change tracking offers several advantages in detecting changed objects and performing incremental backups more efficiently. This option is ideal for buckets with many objects and low change rates.
NetBackup does not need to scan every object in the bucket to check for changes since the last backup. This enables faster backups.
Reduced API costs.
By eliminating full object scans, storage endpoints avoid heavy API traffic, leading to improved overall performance.
Incremental backups become scalable as change detection is independent of the number of objects in the bucket or the size of the bucket.
