point in time. Therefore, the data in the backup would be inconsistent. To eliminate it, Acronis True
Image 2021 creates a so-called snapshot that fixes the data to back up to a particular point in time.
This is done before the backup starts and guarantees that the data is in consistent state.
Select a backup snapshot type from the list:
No snapshot
A snapshot will not be created. The files will be backed up one by one as an ordinary copy
operation.
VSS
Warning! This is the only recommended option for backing up your system. Your computer may not start
after recovery from a backup created with a different snapshot type.
This option is default for disk-level and the Entire PC backups, and guarantees data consistency in
the backup.
Acronis snapshot
A snapshot will be created with the Acronis driver used in previous versions of Acronis True
Image.
VSS without writers
This option is default for file-level backups.
VSS writers are special VSS components for notifying applications that a snapshot is going to be
created, so that the applications prepare their data for the snapshot. The writers are needed for
applications that perform large number of file operations and require data consistency, for
example databases. Because such applications are not installed on home computers, there is no
need to use writers. In addition, this reduces the time required for file-level backups.
4.5.18 Selecting a data center for backup
Location: Options > Advanced > Data center
This option is only available for online backup.
When you create a backup to Acronis Cloud, your data is uploaded to one of the Acronis data centers
located in different countries. Initially, the data center is defined as the one closest to your location
when you create your Acronis account. Afterwards, your online backups and synced files are stored
in the same data center, by default.
We recommend that you set the data center for a backup manually, when you are in a different
country and your default data center is not the closest to your current location. This will significantly
increase the data upload rate.
Note: You cannot change the data center for a pre-existing backup.
To select a data center:
1. On the Online Backup Options screen, click Advanced, and then click Data center.
2. Select the country that is closest to your current location.
