7. Acronis Nonstop Backup
7.1. What is Acronis Nonstop Backup
Acronis Nonstop Backup is a new Acronis True Image Home feature that provides convenient
protection of your disks and files, and allows you to recover from disaster both entire disks and
individual files and even their versions. By default Acronis Nonstop Backup will protect your system
partition, though you can select other partitions and disks to be protected too. Acronis True Image
Home will recommend you the disk (or partition) it considers the best location for storing the backup
data. The storage selection algorithm is similar to that used by the One-Click Backup feature, though
the Acronis Secure Zone cannot be used as the storage for Acronis Nonstop Backup.

Once you start Acronis Nonstop Backup, it will perform an initial image backup of the partition(s)
selected for protection. Having finished this task, Acronis Nonstop Backup will then save changes in
your system and files (including open ones) every five minutes, so you will be able to recover your
system to an exact state in time.

system to an exact state in time.
States of the protected partitions will be backed up at 5-minute intervals for the last 24 hours. The
older backups will be consolidated in such a way that Acronis True Image Home will keep daily
backups for the last 30 days and weekly backups until all Nonstop Backup storage space is used.

The consolidation will be performed every day between midnight and 01:00 AM. The first
consolidation will take place after the Nonstop Backup works not less than 24 hours. For example,
you have turned on the Nonstop Backup at 10:00 AM on September 12. In this case the first
consolidation will be performed between 00:00 and 01:00 AM on September 14. Then the program
will consolidate the data every day at the same time. If your computer is turned off between 00:00
and 01:00 AM, the consolidation will start when you turn the computer on. If you turn off the
Nonstop Backup for some time, the consolidation will start after you turn it on again.

You may think that at these backup rates the storage will fill in no time. Do not worry as Acronis True
Image Home will back up only so called "deltas". This means backing up not entire changed files, but
only differences between new and old versions. 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 a big waste for your storage
space, so Acronis backs up only its changed parts in addition to the initially backed up file.

The program checks partitions and files for changes every five minutes and creates a new time "slice"
only when it finds changes, so the intervals between "slices" can be more than five minutes. In
addition, if, for instance, you are working in Word and do not use the "Save" operation for an hour,
changes in the Word document will not be backed up every five minutes, because the program
checks file changes on the disk and not in the memory.
