the next incremental (p. 268) one. The backups will be combined into a single full backup which will
be dated with the incremental backup's date. Since consolidation may take a lot of time and system
resources, retention rules provide an option to not delete backups with dependencies. In our
example, the full backup will be retained until the incremental one also becomes obsolete. Then both
backups will be deleted.
D
Data catalog
Allows a user to easily find the required version of data and select it for recovery. On a managed
machine (p. 269), users can view and search data in any vault (p. 272) accessible from this machine.
The centralized catalog available on the management server (p. 270) contains all data stored on its
storage nodes (p. 271).
Physically, data catalog is stored in catalog files. Every vault uses its own set of catalog files which
normally are located directly in the vault. If this is not possible, such as for tape storages, the catalog
files are stored in the managed machine's or storage node's local folder. Also, a storage node locally
stores catalog files of its remote vaults, for the purpose of fast access.
Deduplicating vault
A managed vault (p. 269) in which deduplication (p. 265) is enabled.
Deduplication
A method of storing different duplicates of the same information only once.
Acronis Backup can apply the deduplication technology to backup archives (p. 261) stored on storage
nodes (p. 271). This minimizes storage space taken by the archives, backup traffic and network usage
during backup.
Differential backup
A differential backup stores changes to the data against the latest full backup (p. 268). You need
access to the corresponding full backup to recover the data from a differential backup.
Direct management
An operation that is performed on a managed machine (p. 269) using the direct console (p.
264)-agent (p. 261) connection (as opposed to centralized management (p. 263) when the operations
are configured on the management server (p. 270) and propagated by the server to the managed
machines).
The direct management operations include:
creating and managing local backup plans (p. 269)
creating and managing local tasks (p. 269) such as recovery tasks
creating and managing personal vaults (p. 270) and archives stored there
viewing the state, progress and properties of the centralized tasks (p. 264) existing on the
machine
viewing and managing the log of the agent's operations
