Proxmox VE (PVE) can be clustered across multiple server nodes. [27] Since version 2.0, Proxmox VE offers a high availability option for clusters based on the Corosync communication stack. Starting from the PVE v.6.0 Corosync v.3.x is in use (not compatible with the earlier PVE versions).
ZFS (previously Zettabyte File System) is a file system with volume management capabilities. It began as part of the Sun Microsystems Solaris operating system in 2001. Large parts of Solaris, including ZFS, were published under an open source license as OpenSolaris for around 5 years from 2005 before being placed under a closed source license when Oracle Corporation acquired Sun in 2009–2010.

Storage Method: Describes the form in which files are stored in the repository. A snapshot indicates that a committed file(s) is stored in its entirety—usually compressed. A changeset, in this context, indicates that a committed file(s) is stored in the form of a difference between either the previous version or the next.
To avoid downtime, high-availability systems may instead perform the backup on a snapshot—a read-only copy of the data set frozen at a point in time—and allow applications to continue writing to their data. Most snapshot implementations are efficient and can create snapshots in O(1). In other words, the time and I/O needed to create the ...
In Windows Server 2003, VSS is used to create incremental periodic snapshots of data of changed files over time. A maximum of 64 snapshots are stored on the server and are accessible to clients over the network. This feature is known as Shadow Copies for Shared Folders and is designed for a client–server model.
