Incremental backup
1. A backup method used for saving data
changes that occurred since the last
backup version (p. 222) (of any type)
within a backup.
2. A backup process that creates an
incremental backup version (p. 224).
Incremental backup version
A backup version (p. 222) that stores changes
to the data against the latest backup version.
You need access to other backup versions
from the same backup (p. 222) to restore data
from an incremental backup version.
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 (p. 223) and a sequence of
incremental backup versions (p. 224) 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.
O
Online backup
Online backup - a backup that is created using
Acronis True Image Online. Online backups are
stored in a special storage named the Online
storage, accessible over the Internet. The
main advantage of an online backup is that all
backups are stored on the remote location. It
gives a guarantee that all backed up data will
be safe independently of a user local storages.
To begin to use the Online storage a user
should subscribe to the service.
R
Recovery
Recovery is a process of returning of a
corrupted data to a previous normal state
from a backup (p. 222).
V
Validation
An operation that checks whether you will be
able to recover data from a particular backup
version (p. 222).
When you select for validation…
a full backup version (p. 223) - the
program validates the full backup version
only.
a differential backup version (p. 223) - the
program validates the initial full backup
version and the selected differential
backup version.
an incremental backup version (p. 224) -
the program validates the initial full
backup version, the selected incremental
backup version, and the whole chain (if
any) of backup versions to the selected
incremental backup version. If the chain
contains one or more differential backup
versions, the program validates (in
addition to the initial full backup version
and the selected incremental backup
version) only the most recent differential
backup version in the chain and all
subsequent incremental backup versions
(if any) between the differential backup
version and the selected incremental
backup version.
