CBT (Changed Block Tracking)
A feature of VMWare ESX which allows to identify which blocks of the virtual disks have changed and
to transfer only those blocks during the backup/replication process. For example when using CBT
technology, the incremental backup speed can increase up to 20 times.
Cleanup
Deleting backups (p. 85) from a backup archive (p. 86) in order to get rid of outdated backups or
prevent the archive from exceeding the desired size.
Cleanup consists of applying to an archive the retention rules set by the backup task (p. 87) that
produces the archive. This operation checks if the archive has exceeded its maximum size and/or for
expired backups. This may or may not result in deleting backups depending on whether the retention
rules are violated or not.
For more information please refer to the User Guide (p. 27).
Console (Acronis vmProtect Management Console)
The console is the web-based user interface provided by the Acronis vmProtect Agent in order to
access the product functionality. This interface is accessible from any supported Internet browser
after you go to specified URL, for example https://192.168.0.23:9876/, where 192.168.0.23 is the IP
address of Acronis vmProtect Agent (p. 85) and 9876 is the port. Using the direct web-based
console-agent connection, the administrator performs direct management (p. 89).

Datastore
A logical container that holds virtual machine files and other files necessary for operations with
virtual machine. Datastores can exist on different types of physical storage, including local storage,
iSCSI, Fibre Channel SAN, or NFS. A datastore can be VMFS-based or NFS-based.
Deduplication
A method of storing different duplicates of the same information only once.
Acronis vmProtect can apply the deduplication technology to any backup archives (p. 86) of both
Legacy mode (p. 92) and Always Incremental (p. 85) archive formats. This minimizes the storage
space taken by the archives, backup traffic and network usage during the backup.
