Backup Sets

 Home  Previous  Next

A backup set is a set of files (usually a file for a full image of an object and a number of its incremental/differential backups) which R-Drive Image treats as one unit. Backup sets may be used when a number of tasks/scripts are used to create images of the same objects with the same filenames but with different parameters. Backup sets make it possible for you to flexibly control the parameters of complex backup tasks.

You may specify a total size allocated for the image files, a number of image files you want to keep, and the time for which you want to keep the data, etc.

You may do that on the Imaging Mode panel.

Backup sets parameters

Note: R-Drive Image will keep at least one backup set, regardless of the parameters specified.

Zero parameter value disables the parameter.

Backup set size quota

Specifies the total size on the disk in MB allocated for the backup set. If it is exceeded, the older backup set (all its files) will be removed when a new backup set is created.

Maximum number of backup sets

Specifies the number of backup sets If it is exceeded, the older backup sets (all their files) will be removed when a new backup set is created.

Maximum number of image files

Specifies the number of files in all backup sets. If it is exceeded, the older backup sets (all their files) will be removed when a new backup set is created.

Maximum backup set age

Specifies the number of days for which R-Drive Image will keep the oldest backup set. Then the backup set will be removed when a new backup set is created.

Also apply the settings before creating a new image

If  this  option  is  selected,   the  settings will be applied twice, before and after a new image  file  has  been created. For example, if the  number  of files is set  to  2,  and  there  are 2 files already, one file will be deleted before a new image file will be created.

Backup set example

For example, you want to create an image file of your disk with the following conditions:

•A full backup of a disk once a week (Friday, 8:00 PM) and incremental backups on other days at the same time.
•The total size on the disk that may be used to store the image files is 20 GB.
•The number of backup sets is 3, the total number of files not exceeding 30.
•The oldest backup set should be removed in 21 days when a new backup set is created.

Then you need to create two tasks: one for the full data backup on Friday, the second one for the incremental data backup at 8:00 PM on all days except Friday.

The setting should be the following:

On the Image Destination panel

For the both task:

File name:

I:\Test_Image.arc

On the Imaging Mode panel:

For the both task:
