Backup Errors

Thread needs solution

Hi there,
Would love if anyone can email me to assist me here. I have been doing weekly backups for some time but lately i have tons of errors and no backup is working. Not sure where to look for code meanings, but i see the following: Backup Internal Error 458, 784
and many errors above that. Not sure why, backup drive is not full.
Thank you! Attached screen shot.

Hello Sheri,

Thank you for posting your question, I will be happy to help.

To resolve the issue please re-start Acronis scheduler, it appears that the scheduler service has been installed improperly.
- Download a special Acronis utility;
- Start the Command Prompt from Start -> Programs -> Accessories menu;
- Run the following commands in the folder you saved the file to:
schedmgr task zap
schedmgr service stop
schedmgr service uninstall
schedmgr service install
schedmgr service start
This should delete all Acronis tasks on the PC. You should manage your tasks from the scratch. Execute a backup operation and see if the issue remains.
If the issue persists, please download Acronis scheduler, which is a special utility to update the scheduler service. 
Extract the downloaded file, run install.bat and wait for the process to be completed. The utility will automatically update the service. Reboot the computer and re-create the task. The issue should be resolved. 

Please let us know the results, we should be sure that the program runs flawless for you. If the provided information is not clear or if you have any other question do not hesitate to post them and we will be glad to answer.

Thank you.

Both the Acronis and utility links are dead and the scheduler download does not work with Acronis 10. I still do not know of the meaning of error codes 478 and 784 that show up on nearly every backup attempt. How Can I remedy the problem without reasonably easy access to to the meanings of these codes?
