While performing a scheduled backup, you see the error message "Error E7D1001F: Unable to write to file."
To fix this problem, try one of the following solutions. If the issue continues, move to a different step in any order.
If you do not have the appropriate permission's to write to the backup file or folder, this error may occur.
To fix this problem, verify that the logon that you are using has the appropriate rights to write to the file or folder. If your logon account does not have the appropriate rights, use a logon that has sufficient permissions, or store the backup in a location where you do have sufficient rights.
This error may occur if you are using non-alphanumeric characters in your logon password.
Logon passwords with non-alphanumeric characters (as well as blank passwords) are not supported. Change your password to all alphanumeric characters, or use a different logon.
The IRPStackSize parameter on the source or destination computer is too low.
To increase the IRPStackSize parameter, see the document listed for your version of Windows:
- For Microsoft® Windows® 2000, see IRPStackSize Parameter in Windows 2000 (Article ID 285089).
- For Windows XP, see Antivirus software may cause Event ID 2019 (Article ID 177078).
If you see the error message in the Recovery Environment, then changing the IRPStackSize of the other computer can resolve the problem.
In some cases, this error message has been caused by defective RAM. Run a diagnostic test on your RAM to ensure that it is working properly. For more information, see the Microsoft document Windows Memory Diagnostic.
Other possible network problems
This error message can also be caused by other network problems. The following are possible workarounds to resolving this issue:
- Disconnect wireless networking adapters, such as routers or hubs, that are connected between the two computers.
- If you are using the Recovery Environment and you are connecting to the destination computer by name, try connecting by IP address.
For additional information, see the document How to use the recovery environment support utilities.
- Try scheduling the backup for a time when the network traffic is at a minimum.
- Adjust the NIC card and other network hardware speed to 100 Mbps, full-duplex.
