6 Glossary of Terms
B
Backup
1. The same as Backup operation (p. 49).
2. A set of backup versions created and
managed by using backup settings. A
backup can contain multiple backup
versions created using full and
incremental 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. 49).
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 files
created by Acronis True Image Lite 2013 have
a TIB extension. The TIB files resulting from
consolidation (p. 49) of backup versions are
also called backup versions.
Backup version chain
Sequence of minimum 2 backup versions (p.
49) 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).
C
Consolidation
Combining two or more subsequent backup
versions (p. 49) belonging to the same backup
(p. 49) into a single backup version.
The consolidation procedure allows you to
delete the backup versions you no longer
need from any backup chain while maintaining
the consistency of chain's backups. A chain to
be consolidated consists of a full backup and
one or more incremental backups.
Consolidation keeps whichever backups you
choose and deletes any backups that are not
selected. Note that consolidation may take a
lot of time and system resources (including
disk space).
Acronis Nonstop Backup uses a different
consolidation mechanism. In such cases, the
program consolidates the metadata
information it uses for managing the backed
up data. This is because the metadata
information volume is much less than the
backed up data volume. Accordingly,
consolidation requires much less time and
system resources.
N
Nonstop backup
Nonstop backup actually is a disk/partition or
file backup that is created using the Acronis
Nonstop Backup feature. This is a set of one
full backup version and a sequence of
incremental backup versions that are created
at short intervals. It gives almost continuous
protection of data, that is, it allows recovery
of previous data state at any recovery point
you need.
Nonstop protection
Nonstop protection - the process that the
Nonstop Backup feature performs when it is
turned on.
