Thanks. I had looked in dictionary.com and I see now it did give
that but only in the context of a noun. Didn't pay attention.
There was also an M-W entry for journal bearing but when I
clicked on that it said

These are all still nouns, and I remember it used as a verb, maybe
like dbdblockers says.
Journalling, as performed by an NTFS file system, sacrifices user data
that was being written during an interrupted write operation for the
sake of maintaining a "clean" file system.
Under FAT/FAT32, data that was being written during an interrupted
operation can be salvaged, and until that salvage is done the file
system continues to operate just fine because it suffers no real
structural dammage in the process.
I had an NT-4 web server that would nuke 2 weeks worth of IIS log files
any time the server lost power - even though IIS closed each file at the
start of a new day. After the system came back up, the log files were
still there, same time-stamp and file-size, but they were filled will
A journaling file system makes a "journal" of the changes to the file, makes a
copy of the file, then performs the changes. A bit is then set to indicate
the new file is now the real file and erases the "journal" and the old file.
The advantage is that "bit" change is atomic (either it happens or it doesn't
- can't be in between). That atomic write, if successful, completes the
update. If power is lost or the system crashes, you still have the old file,
uncorrupted, *and* the journal so the operation can be retried later.
I asked what journaling is. And most of their answers were about the
noun journal. I think Home Guy figured out what I was thinking of.
Thanks Home Guy and thanks all for the discussion of other meanings.
