Troubleshooting
When you create a network share that you plan to use as a backup storage, please ensure that at
least one of the following conditions is met:
 Windows account has a password on the computer where the shared folder is located.
 Password-protected sharing is turned off in Windows.
You can find this setting at Control Panel —> Network and Internet —> Network and Sharing
Center —> Advanced sharing settings —> Turn off password protected sharing.
Otherwise, you will not be able to connect to the shared folder.
3.5 Using Acronis Nonstop Backup
Acronis Nonstop Backup provides easy protection of your disks and files. It allows you to recover
entire disks, individual files and their different versions.
The main purpose of Acronis Nonstop Backup is continuous protection of your data (files, folders,
contacts, etc.), though you can use it to protect partitions as well. If you choose to protect an entire
partition, you will be able to recover the partition as a whole using the image recovery procedure.
We do not recommend using nonstop backup as a primary way to protect your system. For the safety
of your system, use any other schedule. Refer to Examples of custom schemes (p. 58) for examples
and details.
Nonstop Backup limitations
 You can create only one nonstop backup.
 Acronis Cloud cannot be used as a destination for a disk-level nonstop backup.
 Windows libraries (Documents, Music, etc.) can be protected with a disk-level nonstop backup
only.
 You cannot protect data stored on external hard drives.
 Nonstop Backup and Try&Decide cannot work simultaneously.
How it works
Once you start Acronis Nonstop Backup, the program will perform an initial full backup of the data
selected for protection. Acronis Nonstop Backup will then continually monitor the protected files
(including open ones). Once a modification is detected, the changed data is backed up. The shortest
interval between the incremental backup operations is five minutes. This allows you to recover your
system to an exact point in time.
Acronis Nonstop Backup checks file changes on the disk, not in the memory. If, for instance, you are
working in Word and do not use the "Save" operation for a long time, your current changes in the
Word document will not be backed up.
You may think that at these backup rates the storage will fill in no time. Do not worry as Acronis True
Image 2021 will back up only so called "deltas". This means that only differences between old and
new versions will be backed up and not whole changed files. For example, if you use Microsoft
Outlook or Windows Mail, your pst file may be very large. Furthermore, it changes with each
received or sent E-mail message. Backing up the entire pst file after each change would be an
