I am receiving a message while starting the virtual machine
A couple of things you may want to check to better isolate your concern. First, do let the back up process complete. If it is able to complete the process, then we can say that your program may indeed have no issues. The second best item to run a check on would be the location where the back up resides. Make sure there is enough room and space for the process to complete.
By the way, when the back up process is able to complete and you had a tick on "Do not show this message again" – the prompt should no longer be an issue.
Kristi Natalie and Trosky Timothy, thanks for sharing your knowledge with me. Kristi Natalie, you are right. Actually I made a mistake again and again because I did not tick on the “Do not show this message again” option. For this reason this problem was accruing. But after reading your solution I have understood my fault. Now I am free from this problem.
