B
Backup
1. The same as Backup operation (p. 193).
2. A set of backup versions created and
managed by using backup settings. A
backup can contain multiple backup
versions created using full (p. 194) and
incremental (p. 194) backup methods.
Backup versions belonging to the same
backup are usually stored in the same
location.
Backup operation
An operation that creates a copy of the data
that exists on a machine's hard disk for the
purpose of recovering or reverting the data to
a specified date and time.
Backup settings
A set of rules configured by a user when
creating a new backup. The rules control the
backup process. Later you can edit the backup
settings to change or optimize the backup
process.
Backup version
The result of a single backup operation (p.
193). Physically, it is a file or a set of files that
contains a copy of the backed up data as of a
specific date and time. Backup version of files
created by Acronis True Image 2021 have
a .tibx extension. The TIBX files resulting from
consolidation of backup versions are also
called backup versions.
Backup version chain
Sequence of minimum two backup versions (p.
193) that consist of the first full backup
version and the subsequent one or more
incremental or differential backup versions.
Backup version chain continues till the next
full backup version (if any).
Bootable media
A physical media (CD, DVD, USB drive, or other
media supported by a machine BIOS as a boot
device) that contains standalone version of
Acronis True Image 2021.
Bootable media is most often used to:
 recover an operating system that cannot
start
 access and back up the data that has
survived in a corrupted system
 deploy an operating system on bare metal
 create basic or dynamic volumes on bare
metal
 back up sector-by-sector a disk that has an
unsupported file system

Data synchronization
Data synchronization is a process of keeping
data identical in two or more synchronized
folders. These folders may be located on the
same computer or on different computers
connected via a local network or via the
Internet. When you create, copy, modify or
delete a file or a subfolder in your sync folder,
the same action is automatically done in the
other sync folders. And vice versa - when
something changes in the other sync folders,
the same change is done in your folder.
Differential backup
1. A backup method used for saving data
changes that occurred since the last full
backup version (p. 194) within a backup.
2. A backup process that creates a
differential backup version (p. 193).
Differential backup version
A differential backup version stores changes
to the data against the latest full backup
version (p. 194). You need access to the
corresponding full backup version to recover
the data from a differential backup version.
