A folder’s modification date is updated any time a folder or file is added, changed or removed from it.

My Computer –

Retrospect’s container that holds local volumes available from the backup computer.

My Network Places –

Retrospect’s container that holds network volumes available from the backup computer.

New Backup Set backup –

Allows you to periodically introduce new media into your backups, keeping the original Backup Set media and Catalog intact for archival purposes. A New Backup Set backup copies all selected files to a new Backup Set of the same name as the old, with the addition of a generation number, such as “Backup Set A [001].”

Normal backup –

Retrospect’s usual backup action, performing an incremental backup to copy new or changed files.

Open File Backup –

Retrospect’s Open File Backup allows files to be backed up even if they are opened and being used. This is important to ensure proper backup of server applications such as customer relationship management applications and accounting packages, which are up and running 24 hours a day. For desktop and notebook computers, files such as those that contain e-mail messages or calendar appointments can be backed up while they are in use.

Piton –

Retrospect’s own proprietary protocol for communicating with backup clients. In the live network window, Retrospect uses the Piton name service to establish contact with clients.

Proactive Backup –

Retrospect’s technology allowing flexible, resource-driven or user-initiated backups.

Progressive Backup –

A backup that intelligently copies only files that are new or have changed since the previous backup. Retrospect usually backs up progressively with its Normal backup action. See also matching.

Recycle backup –

A Recycle backup is useful to periodically reset a Backup Set so that it does not grow out of control. A Recycle backup completely erases the Backup Set and Catalog before copying all selected files to the Backup Set. All previous data in the Backup Set is lost.

repeating interval scheduler –

A type of scheduler that lets you schedule a script to repeat automatically at a specified interval of time, such as once every three weeks.

restore –

SMART (Self-Monitoring Analysis and Reporting Technology) –

A technology built in to some hard disk drives that monitors and analyzes a drive’s mechanical attributes over time and attempts to predict and report pending drive failure.

Snapshot –

A Retrospect Snapshot is created during a backup operation to depict a volume’s state (that is, all its files and the folder paths to them). It makes it easy to restore a hard disk to its exact state as of a given backup.

source –

In a backup, duplicate, or archive operation, the volume from which files are copied. In a restore, the Backup Set from which files are copied.

staged backup –

A backup strategy that involves backing up to disk, then transferring the backups to tape. This takes advantage of the benefits of both disk and tape.

subnet –
