2.1 Basic concepts

Backup and recovery

Backup refers to making copies of data so that they can be used to recover the original data after a
data loss event.

Backups are useful primarily for two purposes:



To recover an operating system (p. 12) when it is corrupted or cannot start. This process is called
disaster recovery. For information about protecting your Mac from a disaster, refer to “Backing
up to local or network storage” (p. 7) and “Backing up to Acronis Cloud” (p. 8) for details.



To recover specific files and folders (p. 13) after they have been accidentally deleted or
corrupted.

Backup versions

A backup version is a file created during a backup operation. Each version represents a point in time
to which the system or data can be restored.

The first backup version contains all the data selected for backup. The second and subsequent
versions contain only data changes that occurred since the previous backup version.

Backup file format

When you back up your Mac to a local storage or a network place, True Image saves backup data in
the proprietary .tib format, by using compression. The data from .tib file backups can be recovered
only through True Image.

When you back up your Mac to Acronis Cloud (p. 10), True Image saves your data "as is". You can
open the Acronis Cloud web application (p. 10) on any Mac computer and recover the data.

Schedule

For your backups to be really helpful, they must be as up-to-date as possible. Schedule your backups
(p. 9) to run on a regular basis.

Backup retention rules

Every time you run a backup operation, manually or on a schedule, Acronis True Image creates a new
backup version in the backup location. A maximum of 10 versions are stored in one location. This rule
applies to both Acronis Cloud and local or network folders. When you create the eleventh version,
Acronis True Image automatically deletes the oldest version of the backup. As a result, you always
have the ten most recent backup versions.

Note: In the case of a local or network backup location, you can create more than 10 versions by
setting a new destination for the backup. The versions stored in the previous location will not be
deleted.
