BA4020 Disk I/O error. Disk may run out of space. Check free

by steve.weatherbee » Wed Aug 05, 2015 3:23 am

I have been dealing with this for several weeks now. I have done all of the required troubleshooting.

[*] upgraded to the latest version 8.4.3
[*] purchased new tapes (IBM Ultrium HH5 scsi )
[*] cleaned the tape drive
[*] downloaded ITDT (IBM tape drive utility) ran tests
[*]upgraded tape drive firmware to the latest
[*]downloaded new drivers and installed and tested both

I'm consistently getting the same error (above) This is a windows 2008R2 server.
I've checked the windows logs and see nothing other than the BA software's failure.

Can anyone help?

Hi Steve,

It's Tim from BackupAssist. Sorry to hear that you are having issues with your backup.

For us to troubleshoot this issue for you, please send in system diagnostics for us to review.

To submit diagnostics:

1) Go to Contact Support ( via 'Help > Feedback & Support > Click on Contact Support

2) Fill out the form and ensure that the Submit system diagnostics checkbox at the bottom is checked.

If this does not work:

3) Launch the Diagnostics.exe file located in the BackupAssist install folder: C:\Program Files\BackupAssist v8\Diagnostics.exe

If you do not receive an auto-response email from us or have any issues using our automated support tool please follow these steps to manually send in your diagnostics file:

1. Go to C:\Documents and Settings\All Users\Application Data (for XP and Server 2003)
Go to C:\ProgramData\ (for Vista, Win7 or Server 2008, Server 2012)

2. Email a zipped version of the following folder: BackupAssist vX (Where X is the version that you are running)

If you find this file is too large to e-mail, you can trim down the size of the logs by removing anything older than a week within the following folders under the BackupAssist folder

- Summaries
- History
- Reports
- Temp

The Temp folder, is the default destination for PST and SQL backups to be stored during the backup process, so if there are any of these types of backups contained you can remove these as well as we don't require them.

If the file is up to 300MB in size, you can upload it to for free and send us the download link.
