ST(> Attachment: onlinebackup.html
ST(> functional/design spec based on the input I got on the derby-dev
list.
Very good spec that seems to cover the necessary issues. I have a few
minor comments:
- Log files: I would think you may in some cases have to copy
log files from before the backup checkpoint in order to be
able to roll-back transactions that started before the
backup. (Or am I missing something).
- Jar files: What if a jar file is stored in the database
during backup? Will this be allowed? If yes, how is it
made sure that this is copied into the backup.
- Testing: I think it is important to test that this handles
rollback of transactions correctly. There should be a test
that runs with a higher than normal frequency for
transaction rollbacks.
- Generally, tests should make sure that ACID properties are
guaranteed after a restore.
