single threading
The processing of one transaction to completion before starting the next.
slave node
A node that is not designated as a master node.
snapped file system
A file system whose exact image has been used to create a snapshot file system.
snapped volume
A volume whose exact image has been used to create a snapshot volume.
snapshot
A point-in-time image of a volume or file system that can be used as a backup.
snapshot file system
An exact copy of a mounted file system, at a specific point in time, that is used for online backup. A
snapshot file system is not persistent and it will not survive a crash or reboot of the system.
snapshot volume
An exact copy of a volume, at a specific point in time. The snapshot is created based on disk
mirroring and is used for online backup purposes.
spanning
A layout technique that permits a volume (and its file system or database) too large to fit on a single
disk to distribute its data across multiple disks or volumes.
Storage Checkpoint
An efficient snapshot technology for creating a point-in-time image of a currently mounted VxFS
file system. A Storage Checkpoint presents a consistent, point-in-time view of the file system by
identifying and maintaining modified file system blocks. The Storage Checkpoint facility is an
enabling technology for Block-Level Incremental (BLI) Backup and Storage Rollback.
Storage Rollback
On-disk restore capability for faster recovery from logical errors, such as accidentally deleting a
file. Because each Storage Checkpoint is a point-in-time image of a file system, Storage Rollback
simply restores or rolls back a file or entire file system to a Storage Checkpoint.
