ACRONIS BACKUP AND RECOVERY 10 SERVER FOR LINUX - UPDATE 3 User Manual page 113

a) When creating the first backup plan, specify ServerFiles([DATE]) as the archive name, select the
Name backup files using the archive name... check box, select Full as the backup type, and
schedule the backups to run every day at 01:00:00 AM.
b) When creating the second backup plan, specify the same settings as in the first backup plan, but
select Differential as the backup type and schedule the backups as follows:

Run the task: Daily

Every: 1 Hour(s)
 From: 08:00:00 AM
 Until: 05:01:00 PM
Result:

The full backup of January 31, 2011, will be stored as ServerFiles(1.31.2011).tib.
 The 10 differential backups of January 31, 2011, will be stored as ServerFiles(1.31.2011)2.tib,
ServerFiles(1.31.2011)3.tib, and so on up to ServerFiles(1.31.2011)11.tib.

The following day, February 1, the backups will start with the full backup
ServerFiles(2.1.2011).tib. The differential backups will start with ServerFiles(2.1.2011)2.tib.
See also "The [Date] variable" (p. 113).
6.2.8.2 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, copy, move, delete the
backups manually or by using a script.
The date format is m.d.yyyy. For example, it is 1.31.2011 for January 31, 2011. (Note absence of
leading zeros.)
You can place this variable anywhere in the archive name. You can use both lowercase and
uppercase letters in this variable.
Examples
Example 1. Suppose that you perform incremental backups twice a day (at midnight and noon) for
two days, starting on January 31, 2011. If the archive name is MyArchive-[DATE]-, here is the list of
backup files after day two:
MyArchive-1.31.2011-.tib (full, created on January 31 at midnight)
MyArchive-1.31.2011-2.tib (incremental, created on January 31 at noon)
MyArchive-2.1.2011-.tib (full, created on February 1 at midnight)
MyArchive-2.1.2011-2.tib (incremental, created on February 1 at noon)
Example 2. Suppose that you perform full backups, with the same schedule and archive name as in
the previous example. Then, the list of backup files after day two is the following:
MyArchive-1.31.2011-.tib (full, created on January 31 at noon)
MyArchive-2.1.2011-.tib (full, created on February 1 at noon)
