snapshot

A consistent point-in-time view of a volume that is used as the reference point for the backup operation. After a snapshot is created, the primary data can continue being modified without affecting the backup operation.

A stable disk copy of the data prior to backup. A snapshot is created very rapidly, causing minimal impact on other applications. There are two basic types: copy-on-write and mirror.

Typically refers to a point-in-time logical copy of a storage object implemented in software.

A TimeImage of the production storage.

An image file of a source computer created by AI Snapshot before or after installation of a software application. Two snapshots are compared and used to create a configuration file that captures the changes made to the source computer.

When you create a Snapshot package, you take a Snapshot of the system, install the application, take a second Snapshot, and compare the two Snapshots. The Streaming Composer processes the difference between the two Snapshots to collect the contents of the Package.

A file in which information about the system’s configuration and properties is stored.

A point-in-time image of a volume or file system that can be used as a backup.

A point-in-time image or replica of a file system that looks identical to the file system from which the snapshot was taken.
