Hi Jeff, we create a backup of the entire /usr/afs/db directory every night (and in addition every night we make a copy of the boot drive of our database servers onto an alternate drive). Is there anything more to be gained by using pt_util? What is the difference between making a copy of /usr/afs/db/prdb.DB and prdb.DBSYS1, and running pt_util? Also, is there documentation (besides pt_util -h) for this command?
Merely copying the database file is not atomic, so there's the chance when you make a copy that it will not be internally consistent. If you use pt_util, it will check the database version before and after the dump, and print a warning if they are not the same. Of course, this only helps if you notice the warning...
In addition, the dump file created by pt_util is (more or less) human readable. So, if an admin accidentally deletes himself, you can read the latest dump to see what his PTS ID was and what groups he was in.
No, I don't think there is any documentation. As I recall, pt_util was originally an internal tool developed at MIT, which was contributed to OpenAFS as-is.
