Re: lib-ir: Needs for Scholars Bank: backup/validation procedures

[Corey Harper <charper@darkwing.uoregon.edu>]

A good starting point for this kind of documentation can be found in the
documentation of CONTENTdm backup procedures, posted to the MIG list in
May 2004:

http://darkwing.uoregon.edu/~catdept/meta-data/msg00097.html

The sections on tape and incremental backups have been applicable to
Scholars' Bank since we managed to free up a backup license to devote to
IR backup.  I can investigate a bit further to determine whether the
cycle of tape re-use parallels what is done for libweb and ambrosia, but
I suspect it does.  

The only real difference is that there is an additional step involving an
SQL dump from the database.  This is because databases don't back up
well.  The dump can be thought of as a snapshot of the database that
can used to recreate the database structure and content from
scratch.  These files are also generated for use in transferring
Scholars' Bank data to irtest, our DSpace development instance.

OIA exports are made from the collection periodically as well, but they
are stored locally on my desktop.  I don't see much utility in
storing these in a more permanent or stable location, as they are
considerably less useful than the SQL dumps.
