> Ideally, incremental backups, or a base snapshot and a number of snapshot deltas, become abstract concepts in ACS, and drivers for primary storage can implement the operations for the abstract concepts. > > My background is LINSTOR. LINSTOR leverages LVM's dm-thin to take snapshots; it uses [thin-send-recv](https://github.com/LINBIT/thin-send-recv/commits/master/) to generate snapshot deltas. You can find more about it [here](https://linbit.com/drbd-user-guide/linstor-guide-1_0-en/#s-linstor-scheduled-backup-shipping) > > But of course, many other primary storage solutions that are available for ACS probably also support continuous preservation of snapshot-deltas. I'm not sure I got your point @Philipp-Reisner, but I'll not be touching any storage drivers in this implementation. This will be the native ACS implementation for NFS/Local/SharedMountPoint storages. We have plans to add incremental snapshots for Ceph, but then we will have to use Ceph's back-end for it. If others want to implement this feature for other drivers, they are free to do so. -- This is an automated message from the Apache Git Service.
