Back up your old disk drive, and then recover it to the new one.
Backup file format
Acronis True Image usually saves backup data in the proprietary tib format using compression. The
data from .tib file backups can be recovered only through Acronis True Image, in Windows or in the
recovery environment.
Acronis Nonstop Backup uses a special hidden storage for data and metadata. The backed up data is
compressed and split into files of about 1 GB. These files also have a proprietary format and the data
they contain can be recovered only with the help of Acronis True Image.
Backup validation
The backup validation feature allows you to confirm that your data can be recovered. The program
adds checksum values to the data blocks being backed up. During backup validation, Acronis True
Image opens the backup file, recalculates the checksum values and compares those values with the
stored ones. If all compared values match, the backup file is not corrupted. Refer to Validating
backups (p. 61) for details.
Scheduling
For your backups to be really helpful, they must be as "up-to-date" as possible. Schedule your
backups to run automatically and on a regular basis. Refer to Scheduling (p. 42) for details.
Deleting backups
When you want to delete backups and backup versions you no longer need, please do it by using the
tools provided by Acronis True Image 2016. We recommend that you configure automatic cleanup
rules when customizing the backup scheme.
Acronis True Image 2016 stores information on the backups in a metadata information database.
Therefore, deleting unneeded backup files in Windows Explorer will not delete information about
these backups from the database. This will result in errors when the program tries to perform
operations on the backups that no longer exist.
Refer to Deleting backups and backup versions (p. 63) for details.
3.2 The difference between file backups and
disk/partition images
When you back up files and folders, only the files and folder tree are compressed and stored.
Disk/partition backups are different from file and folder backups. Acronis True Image 2016 stores an
exact snapshot of the disk or partition. This procedure is called "creating a disk image" or "creating a
disk backup" and the resulting backup is often called "a disk/partition image" or "a disk/partition
backup".
What does a disk/partition backup contain?
A disk/partition backup contains all the data stored on the disk or partition:
1. Zero track of the hard disk with the master boot record (MBR) (applicable to MBR disk backups
only).
2. One or more partitions, including:
1. Boot code.
