Network connection transfer rate
When you back up data to Acronis Cloud, you can change the connection speed used by Acronis True
Image 2021. Set the connection speed that will allow you to use Internet and network resources
without annoying slowdowns.
To set up the connection speed, select one of the following options:
Maximum
The data transfer rate is maximum within a system configuration.
Limit to
You can specify a maximum value for data upload speed.
Snapshot for backup
This option is for advanced users only. Do not change the default setting if you are not sure which option to
choose.
During a disk or partition backup process, which often takes a long time, some of the backed-up files
may be in use, locked, or being modified in one way or another. For example, you may work on a
document and save it from time to time. If Acronis True Image 2021 backed up files one by one, your
open file would likely be changed since the backup start, and then saved in the backup to a different
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.
