Rotating backup scheme using external drives
Nov 7, 2014
In this article we will show you how to set Backup4all to backup
on two external drives using the backup
destination rotation scheme, in case Windows assigns different
drive letters for each external drive, even ifthey are not
connected at the same time. Backup4all will verify which
removable/external drive is connected
at the backup time. If one of the correct drive is connected,
the backup will run; otherwise the backup will
abort.
Summary
In this article we will show you how to set Backup4all to backup
on two external drives using the backup
destination rotation scheme, in case Windows assigns different
drive letters for each external drive, even if
they are not connected at the same time. Backup4all will verify
which removable/external drive is connected
at the backup time. If one of the correct drive is connected,
the backup will run; otherwise the backup will
abort.
The solution is to mount the external drives to the same local
folder and run the backup to that folder. When
running the backup, a script will be executed before the backup,
so the connected external drive will be
mounted to that folder. After the mount is made, the backup will
run.

How to create the script
You need to create script and run it before the backup. That
will check the existence of the volumeID of the
backup drives and after that it will run (or abort) the
backup.
Steps to follow:
1. Create a folder where we want to map the disks. The backup
job will back up to this folder.
In this tutorial we will use C:\DiskMount
2. Get the volume GUID for each external disk.
Plugin both disks. Start cmd.exe and type this command:
mountvol c:\DiskMount
Note the volume for the drive letter associated with each
external drive letter.
It should look like:

\\?\Volume{964ee7c8-dbfd-11e3-82cd-74d02b7dfc4e}\
3. Create a small batch script containing these lines:
REM unmount first
mountvol C:\DiskMount /D
REM try mount first drive (it will mount label W); fails if disk
is not online
mountvol C:\DiskMount
\\?\Volume{301547fa-2c57-11e4-8317-f2b8544bc870}\
REM try mount second drive (it will mount label V); fails if
disk is not online
mountvol C:\DiskMount
\\?\Volume{aeb73438-7f5c-11e3-8283-74d02b7dfc4e}\
4. Save the script as C:\scripts\mount.bat
