Backup and Disaster Recovery with K3s and MicroK8s 4
Backup Dedupe
Backup dedupe is a critical feature in any backup and disaster recovery solution. K3s and MicroK8s 4 provide built-in support for backup dedupe, which eliminates duplicate data and reduces storage requirements.
How Backup Dedupe Works
Backup dedupe works by identifying and eliminating duplicate data blocks within a backup set. This process is typically done at the block level, where each block is compared to other blocks in the backup set. If a duplicate block is found, it is replaced with a reference to the original block.
