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 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:
On the Imaging Mode panel: For the both task:
For the full data backup task
For the incremental backup task
On the Time/Event panel: For the full data backup task
For the incremental backup task
File name convention:
N is the number of incremental backup The files created
Please note, that the oldest backup set would be deleted if the total size exceeds 20 GB or the number of all files from all backup sets exceeds 30.
