Snapshot provider

A snapshot provider is a service R-Drive Image uses to read the disk content while creating its image. R-Drive Image uses the snapshot providers in the order specified on the tab. If it fails to use the first one selected, it tries to use the second one, and so on.

Windows Volume Snapshot Service

If this check box is selected, R-Drive Image will try to use the Windows native snapshot provider. This snapshot provider is able to notify system applications that a snapshot is being taken.

If this option is selected, pagefile.sys and hibernate.sys files are excluded from the image of the system disk .

R-TT Volume Snapshot Service

If this check box is selected, R-Drive Image will try to use R-TT snapshot provider. This snapshot provider is not able to notify system applications that a snapshot is being taken.

Notify system applications

If this check box is selected, the snapshot provider, if it supports this feature, notifies system applications that a snapshot is being taken.

Limit I/O rate

Specifies the rate limits for reading/writing data from/to disks

Limit read

The rate limit for reading from the source disk

Limit write

The rate limit for writing to the destination disk

Process priority

These options specify how much computer resources R-Drive Image will consume during a backup process.

Backup Process Priority

Specifies the priority of the backup process. Similar to that specified in Windows Task Manager.

Use CPU cores

Specifies how many processor cores R-Drive Image will use for the backup process.

Ignore disk read errors (bad sectors)

If this check box is selected, R-Drive Image will ignore possible read errors when it tries to read data from bad sectors.

R-Drive Image works with disks with bad sectors in the following way:

It reads a certain part of disk (predefined by Windows) and

• If read errors are ignored, the entire part with bad sectors will be filled with zeros.

• If read errors are not ignored, R-Drive Image reads that part sector by sector and shows a warning message for every bad sector with two options: skip the sector or try to read it again. In this case only the bad sectors will be filled with zeros, but all that requires manual actions and extremely slows the imaging process.

Please note that R-Drive Image is developed for the work with normally functioning disks. If you need to image a malfunctioning disk, use R-Studio , a data recovery utility. It has more controls for imaging, and can create R-Drive Image -compatible images even in its demo mode, that is, without registering.

Backup AUX applications

R-Drive Image is able to make applications run before and after all backup operations. Please note that those application should return a 0 exit code. Leave these fields blank if in doubt.

Before

An application R-Drive Image starts before the backup operations starts. If you need to start several applications, you may use a command file.

Example: "cmd.exe /c example.bat"

After

An application R-Drive Image starts after the backup operations completes. If you need to start several applications, you may use a command file.

Example: "cmd.exe /c example.bat"

Snapshot AUX applications

R-Drive Image is able to make applications run before and after taking the snapshot of one or several volumes. Please note that those application should return a 0 exit code. Leave these fields blank if in doubt.

Before

An application R-Drive Image starts before it takes the snapshot of one or several volumes. If you need to start several application, you may use a command file.

Example: "cmd.exe /c example.bat"

After

An application R-Drive Image starts after it takes the snapshot of one or several volumes. If you need to start several application, you may use a command file.

Example: "cmd.exe /c example.bat"
