When you use simplified file naming
 The file name of the first (full) backup in the archive will consist of the archive name; for
example: MyData.tib. The file names of subsequent (incremental or differential) backups will
have an index. For example: MyData2.tib, MyData3.tib, and so on.
This simple naming scheme enables you to create a portable image of a machine on a detachable
media or move the backups to a different location by using a script.
 Before creating a new full backup, the software will delete the entire archive and start a new
one.
This behavior is useful when you rotate USB hard drives and want each drive to keep a single full
backup (p. 56) or all backups created during a week (p. 57). But you might end up with no
backups if a full backup to your only drive fails.
This behavior can be suppressed by adding the [Date] variable (p. 54) to the archive name.
When you use standard file naming
 Each backup will have a unique file name with the exact time stamp and the backup type. For
example: MyData_2010_03_26_17_01_38_960D.tib. This standard file naming allows for a wider
range of backup destinations and backup schemes.
Restrictions
Simplified file naming is not available if you back up to Acronis Secure Zone or Acronis Cloud Storage.
When using simplified file naming, the following functionality is not available:
 Setting up full, incremental and differential backups within a single backup plan. You need to
create separate backup plans for each type of backup.
 Setting up replication of backups.
 Setting up retention rules.
 Setting up regular conversion of backups to a virtual machine.
 Converting an incremental or differential backup into a full one.
Restrictions on archive names
 The archive name cannot end with a number.
 The FAT16, FAT32, and NTFS file systems do not allow the following characters in the file name:
backslash (\), slash (/), colon (:), asterisk (*), question mark (?), quotation mark ("), less than
sign (<), greater than sign (>), and pipe (|).
4.3.1 The [DATE] variable
If you specify the [DATE] variable in the archive name, the file name of each backup will include that
backup’s creation date.
When using this variable, the first backup of a new day will be a full backup. Before creating the next
full backup, the software deletes all backups taken earlier that day. Backups taken before that day
are kept. This means you can store multiple full backups with or without incremental ones, but no
more than one full backup per day. You can sort the backups by date. You can also use a script to
copy, move, or delete the older backups.
The value of this variable is the current date surrounded by brackets ([]). The date format depends on
the regional options on the machine. For example, if the date format is year-month-day, the value for
January 31, 2012, is [2012-01-31]. Characters that are not supported in a file name, such as slashes
(/), are replaced with underscores (_).
