Bootable media
A physical media (CD, DVD, USB flash drive or
other media supported by a machine BIOS as a
boot device) that contains standalone version
of Acronis True Image Home 2011.
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
C
Consolidation
Combining two or more subsequent backup
versions (p. 222) belonging to the same
backup (p. 222) 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.
D
Differential backup
1. A backup method used for saving data
changes that occurred since the last full
backup version (p. 223) within a backup.
2. A backup process that creates a
differential backup version (p. 223).
Differential backup version
A differential backup version stores changes
to the data against the latest full backup
version (p. 223). You need access to the
corresponding full backup version to recover
the data from a differential backup version.
Disk backup (Image)
A backup (p. 222) that contains a sector-based
copy of a disk or a partition in packaged form.
Normally, only sectors that contain data are
copied. Acronis True Image Home 2011
provides an option to take a raw image, that
is, copy all the disk sectors, which enables
imaging of unsupported file systems.
F
Full backup
1. A backup method that is used to save all
the data selected to back up.
2. A backup process that creates a full
backup version (p. 223).
Full backup version
A self-sufficient backup version (p. 222)
containing all data chosen for backup. You do
not need access to any other backup version
to recover the data from a full backup version.
I
Image
The same as Disk backup (p. 223).
