Unknown error when using cpio

[martvar]

I used cpio command to backup some files,
find . -print | cpio -ov > backup.cpio 2>errmsg
In errmsg I got processed file names
and the end was:
7889920 blocks
1 error(s)
But I couldn't find any error message searching
whole errmsg file.
What error is cpio reporting?

It might have to do with the fact that your command is being executed in the directory that you are backing up.

I would try going up one directory level and if, for example, the directory you want to back up is named "keepers", then run the command:

find keepers -print | cpio -ov > backup.cpio 2>errmsg

Does that still have the error message? If so, then it may be that one of the files that you are trying to backup is being written to at the same time you are trying to back it up.
