(9875) Recovering from BACKUP errors?

[User]

We make backups everyday and sometimes be have a %X10A38012 error without any special reason and in the same circumstances.

If we repeat the backup at the end of the first, it is done correctly. The explanation for the error is: "The Backup utility cannot open the specified output file" but this does not have too much meaning. It happens specially with large files, but the destination drive has enough space.

Thanks.

You have likely reached your open file or channel limit. Reaching these limits can also be the reason why the message isn't translated into text - with insufficient resources for the file open, there are also insufficient resources to open the message file containing the text translation.

In general, please follow the documentation on setting up a BACKUP username as documented in the system manager's essentials manual. In particular, make certain your FILLM quota is set to a value of CHANNELCNT parameter minus 20.
