What is Snapshot-File Backup?

Snapshot-File Backup is a data backup service based on Snapshot technology, used to protect and manage data on virtual servers (VPS) and physical servers (Dedicated Server).
Snapshot technology allows creating static copies of the system or specific files at a certain time. Snapshot data is stored on a network file system (NFS) so customers can easily retrieve Backup data from Local.

How does Snapshot-File Backup work?

Snapshot-File Backup
  • Create Snapshot: When the create snapshot command is executed, the system creates a static copy of the data at that time.
  • Copy-on-Write: After a snapshot is created, any changes to the original data are written back to new data blocks. Original data blocks that have not changed will remain in the snapshot.
  • Stored on NFS: Snapshots are stored on a network file system (NFS). NFS allows remote access to snapshots without copying data locally. This makes it easy to manage and access snapshots from many different devices.
  • Data recovery: When data recovery is needed, snapshots can be used to restore the system to the state at the time it was taken.
  • Snapshot management: Based on virtualization manager support, users can schedule snapshots to automatically create, view, download or delete snapshots to save storage space.
