has zfs diff and zfs send -i for incremental streams. Internally, ZFS uses transaction groups and block pointers to identify changed blocks.
For , the most practical CBT-like approach is: LVM thin snapshots + thin_delta or Btrfs/ZFS with incremental send . 5. Practical Implementation: LVM Thin CBT Script Here’s a minimal script demonstrating CBT concept using LVM thin. linux cbt
Here’s a technical write-up on — its concepts, implementation options, and practical usage for incremental backups. Linux Change Block Tracking (CBT): A Technical Overview 1. Introduction Change Block Tracking (CBT) is a mechanism that identifies which blocks on a storage device have been modified since a particular point in time. It enables efficient incremental backups by allowing backup software to read only changed data instead of scanning entire volumes. has zfs diff and zfs send -i for incremental streams
