Simple Rotation Schemes

These scheme types are available in all R-Drive Image versions:

The following simple rotation schemes can be used:

No rotation

No rotation

Specifies how the data will be written to an existing image file.

Incremental: Select this option to preserve the data in the existing image file and append only changes. Appended changes will be those between the last saved changes and the current state. You may restore data as they were on each time of data imaging.

Differential: Select this option to preserve the data in the existing image file and append only changes. Appended changes will be those between the first saved full image and the current state. You may restore data as they were on each time of data imaging.

Overwrite: Select this option if you want to completely replace the data in the image file.

Minimum file sizes: If you need to keep only the latest backup instant, you may use the D differentially option and delete all previous differential files. If you need to keep all instances, you may use the Incrementally option to keep overall file sizes smaller.

Data safety: If any of the differential file is damaged, data will be lost only for that backup instant. If any of the incremental file is damaged, data will be lost for all subsequent backup instances starting from the damaged file until the next full of differential backup.

Rotation scheme outcome: the first image will be a full one, the rest images will be differential ones.

Imaging mode	Full: All data in the image file will be replaced with the current one. Differentially: Appended changes will be those between the saved full image and the current state. If there is no full image, it will be created instead. When restoring data, you will need the full image and ONLY the differential file created at the instant to which you want to restore data. Incrementally: Appended changes will be those between the last saved changes and the current state. If there is no full image, it will be created instead. When restoring data, you will need the full image and ALL files (both incremental and differential ones) created to the instant to which you want to restore data. Minimum file sizes: If you need to keep only the latest backup instant, you may use the D differentially option and delete all previous differential files. If you need to keep all instances, you may use the Incrementally option to keep overall file sizes smaller. Data safety: If any of the differential file is damaged, data will be lost only for that backup instant. If any of the incremental file is damaged, data will be lost for all subsequent backup instances starting from the damaged file until the next full of differential backup.
Full image every	Specifies the number of differential/incremental images after which a full image will be created.
Maximum number of full images	Specifies the number of full images. If it is exceeded, the older full backup files will be removed.
Maximum age of full images	Specifies the number of days for which R-Drive Image will keep full image files. Then the files will be removed.
Maximum number of image files	Specifies the number of image files. If it is exceeded, the older files will be removed.
Maximum size of all image files	Specifies the total size of all files. If it is exceeded, the older files will be removed.
Apply quota	Before & After imaging: the settings will be applied before creating the image, but as if it's already been created. For example, if the number of files is set to 3, and there are already 3 files,the oldest file will be deleted before creation of the new image file. After imaging: R-Drive Image will create the image file first, then deletes the oldest file.
Always leave first full image	If this option is selected, the very first image will always be kept.

Note: when a full image file is deleted according to the specified options, R-Drive Image deletes all differential/incremental image files related to that full image.

Rotation scheme outcome: the first image will be a full one, then next 6 images will be differential ones, then another full image, followed by 6 differential images. One full image and all respective differential imaged will be deleted when 3 full images have been created, You may see the outcome of this scheme on the An example of a rotation scheme help page.

Grandfather-Father-Son scheme

Keep Daily images	Specifies the number of days for which R-Drive Image will keep Daily image files. Then the files will be removed.
Keep Weekly images	Specifies the number of weeks for which R-Drive Image will keep Weekly image files. Then the files will be removed.
Keep Monthly images	Specifies the number of months for which R-Drive Image will keep Monthly image files. Then the files will be removed.
Maximum size of all image files	Specifies the total size of all files. If it is exceeded, the older files will be removed.
Apply quota	Before & After imaging: the settings will be applied before creating the image, but as if it's already been created. For example, if the number of files is set to 3, and there are already 3 files,the oldest file will be deleted before creation of the new image file. After imaging: R-Drive Image will create the image file first, then deletes the oldest file.
Always leave first full image	If this option is selected, the very first image will always be kept.

Rotation scheme outcome: the first image will be a full one, then every day a incremental image, every week a differential image, every month a full image. All incremental images will be deleted when a differential image has been created. All differential images will be deleted when a monthly image has been created. The oldest full image and respective differential / incremental images will be deleted in 3 months.

Tower-of-Hanoi

Tower-of-Hanoi scheme

Rotation scheme outcome: the first image will be a full one, the next image will be the differential one, then an incremental one. A full image will be created in 4 images. The the rest of the images will be deleted.
