VSS process

FlashSnap integrates with Volume Shadow Copy Service as both a VSS Requestor and a VSS Provider.

The following steps occur, in the order presented, during the snapshot process:

  • Acting as a VSS Requestor, FlashSnap notifies Enterprise Vault to put Enterprise Vault components in to backup mode (read-only mode).

  • Acting as a VSS Requestor, FlashSnap notifies the VSS coordinator service to prepare for a split-mirror snapshot of SQL or a volume.

  • The VSS coordinator service calls the SQL Writer to find out which volumes contain the databases and transaction logs (if the snapshot set involves an SQL database).

  • The VSS coordinator service notifies the FlashSnap VSS Provider to prepare for the snapshot.

  • Acting as a VSS Requestor, FlashSnap requests that the VSS coordinator service begin the snapshot call.

  • The VSS coordinator service notifies the SQL writer to quiesce and freeze the components in preparation for the snapshot (if the snapshot set involves an SQL database).

  • The VSS coordinator flushes the file system buffer and then freezes the file system. which ensures that file system metadata is written and that the data is written in a consistent order.

  • The VSS coordinator service calls the FlashSnap Provider to create the snapshot by detaching the snapshot volume from the original volume. After the snapshot volume is detached, the FlashSnap Provider informs the VSS coordinator service to proceed.

  • The VSS coordinator Service thaws the file system (release the freeze of the file system).

  • The VSS coordinator service notifies SQL to thaw (release the freeze) and resume normal I/O (if the snapshot set involves an SQL database).

  • Acting as a VSS Requestor, FlashSnap notifies the Enterprise Vault to clear Enterprise Vault components from backup mode (read-only mode).

The following steps occur, in the order presented, during the restore process:

  • Acting as a VSS Requestor, FlashSnap notifies the Enterprise Vault to put Enterprise Vault components into backup mode (read-only mode).

  • Acting as a VSS Requestor, FlashSnap notifies the VSS coordinator service to prepare for a restore operation.

  • The VSS coordinator service calls SQL which prepares for the restore operation (if the snapshot set involves an SQL database).

  • The FlashSnap utility restores the snapshot volumes. After the snapback operation completes, the FlashSnap utility informs the VSS coordinator service to proceed.

  • The VSS coordinator service notifies SQL to process the post-restore operations (if the snapshot set involves an SQL database)

  • Acting as a VSS Requestor, FlashSnap notifies Enterprise Vault to clear all Enterprise Vault components from backup mode (read-only mode).
