Volume Shadow Copies with CephFS: A Samba-Centric Approach
summary
CephFS exposes snapshots as Windows Volume Shadow Copies using the vfs_ceph_snapshots Samba module, tested against a 3-node CephFS cluster and a Windows client showing enumeration and restoration via the Previous Versions UI. The integration supports both kernel mount and libcephfs/VFS modes with different samba configs, requires cluster quiesce before snapshot creation, and demonstrates create/list/restore workflows. The feature works but remains experimental, not enabled by default, and needs wider testing and bug reports before production use.
