Unified API for Snapshotting File Systems


One Line Summary

Let's talk about generic API for snapshots.


Some file and storage systems (Btrfs, Nilfs, LVM and out-of-tree Next3) already support snapshots. Other file systems (Ext4) may gain snapshots support in the near future.

Every snapshotting file or storage system uses it’s own user tools for managing and mounting snapshots.

For the sake of applications that would like to take snapshots regardless of the storage type (like backup applications), it would be useful to have a generic snapshots API.
