Backup Failure

Recommended Posts

I have a recurring problem with one of my files when I try to back it up. Everything works fine for a day or so and then, when I'm prompted to back up the file and click yes, I get a VW message "Internal Error - general failure encountered during disk I/O operation (failure on attempt to open file)". I end up going back into the most recent of my saved daily copies of the file, duplicate that saved file and begin using that as a new base file. This works fine for a day or so, and then the same backup problem starts again. Any suggestions? I'm way too far along on this project to start over with a brand new file.

Are you saving to a local drive? External drive? Network?

I'm using VW 2008, Mac OS 10.4.11 and am backing up directly to the hard drive of the computer I'm working on. I later save a copy to an external hard drive. This is not a problem when I Save the file, just when VW wants to create a back up file.

How much free space do you have on the drive? What are the permissions on the folder you are saving to?

When I have seen something like this before it was trying to backup to a non-existant location. Are you changing file or folder names?

I use a single folder in my Documents folder to store all of my backups, have it set to keep the last 12 backups, backup every 5 minutes, and backup without asking.

Thanks Pat. I've got plenty of free space. Tried re-directing the backups to a new, specific folder but got the same message. Would there be a problem if the file I'm using now is a copy of a file?

It could. If you need to revert to a backup, I recommend that you drag the backup file to a different location before you open it.
