Copyright © Acronis, Inc., 2000-2009 209Agent (Acronis Backup & Recovery 10 Agent)An application that performs data backup and recovery and enables other management operationson the machine (p. 217), such as task management and operations with hard disks.The type of data that can be backed up depends on the agent type. Acronis Backup & Recovery 10includes the agents for backing up disks and files and the agents for backing up virtual machinesresiding on virtualization servers.Agent-side cleanupCleanup (p. 213) performed by an agent (p. 209) according to the backup plan (p. 210) that producesthe archive (p. 209). Agent-side cleanup is performed in unmanaged vaults (p. 221).Agent-side validationValidation (p. 221) performed by an agent (p. 209) according to the backup plan (p. 210) thatproduces the archive (p. 209). Agent-side validation is performed in unmanaged vaults (p. 221).ArchiveSee Backup archive (p. 209).BBackupThe result of a single backup operation (p. 209). Physically, it is a file or a tape record that contains acopy of the backed up data as of specific date and time. Backup files created by Acronis Backup &Recovery 10 have a TIB extension. The TIB files resulting from backup consolidation (p. 213) are alsocalled backups.Backup archive (Archive)A set of backups (p. 209) created and managed by a backup plan (p. 210). An archive can containmultiple full backups (p. 216) as well as incremental (p. 217) and differential backups (p. 213).Backups belonging to the same archive are always stored in the same location. Multiple backup planscan back up the same source to the same archive, but the mainstream scenario is "one plan – onearchive".Backups in an archive are entirely managed by the backup plan. Manual operations with archives(validation (p. 221), viewing contents, mounting and deleting backups) should be performed usingAcronis Backup & Recovery 10. Do not modify your archives using non-Acronis tools such as WindowsExplorer or third-party file managers.Backup operationAn operation that creates a copy of the data that exists on a machine's (p. 217) hard disk for thepurpose of recovering or reverting the data to a specified date and time.
