# Snapshotters
|
|
|
|
Snapshotters manage the snapshots of the container filesystems.
|
|
|
|
The available snapshotters can be inspected by running `ctr plugins ls` or `nerdctl info`.
|
|
|
|
## Core snapshotter plugins
|
|
|
|
Generic:
|
|
- `overlayfs` (default): OverlayFS. This driver is akin to Docker/Moby's "overlay2" storage driver, but containerd's implementation is not called "overlay2".
|
|
- `native`: Native file copying driver. Akin to Docker/Moby's "vfs" driver.
|
|
|
|
Filesystem-specific:
|
|
- `btrfs`: btrfs. Needs the plugin root (`/var/lib/containerd/io.containerd.snapshotter.v1.btrfs`) to be mounted as btrfs.
|
|
- `zfs`: ZFS. Needs the plugin root (`/var/lib/containerd/io.containerd.snapshotter.v1.zfs`) to be mounted as ZFS. See also https://github.com/containerd/zfs .
|
|
- `devmapper`: ext4/xfs device mapper. See [`devmapper.md`](./devmapper.md).
|
|
|
|
[Deprecated](https://github.com/containerd/containerd/blob/main/RELEASES.md#deprecated-features):
|
|
- `aufs`: AUFS. Deprecated since containerd 1.5. Planned to be removed in containerd 2.0. See also https://github.com/containerd/aufs .
|
|
|
|

|
|
- `overlaybd`: [OverlayBD Snapshotter](https://github.com/containerd/accelerated-container-image)
