Backup change for even and odd week numbers

Thread needs solution

Hi all togehter,

I have a Update's configured to use two Usb Drives wich are set to K: and J:

Only one ist connected at the time and i would like to change them on every Friday so i have so my backup's should go on week one to Drive J: and on week two to Drive K:

Peter, how many backup tasks are you using here with these two rotating drives?

See KB 62741: Acronis True Image: rotating backup destination disks requires separate backup plans per destination disk

If you are using two separate backup tasks, one per backup drive, then you would have to try to adapt the existing scheduling options, i.e. pick Monthly then select the specific days in each month that correspond with the Fridays to run the backup, but modify this each month!

The other approach would be to have a Pre Command batch file that checks for the presence of the correct backup drive and only runs the task when it is connected.

A simple batch file might be as follows: CheckDrive.bat

echo off
if not exist K: goto nodrive
dir K:
echo "Drive found!"
exit /b 0

:nodrive
echo "Drive not found!"
exit /b 1

You could try the option of running the backup task when the backup device is connected. I tested this on my (now aging) Dell notebook and it worked OK. The only drawback was that if I left the USB sick connected to ran the backup each time I started the notebook. However, the solution suggested by Steve Smith has greater flexibility.
