Subject Re: [IB-Architect] Super-transactions and Incremental Backup
Author Ann Harrison
Just for information:

transaction ids do not survive backup/restore

dbkeys do not survive backup/restore

the permanent (until backup/restore) record of
a transaction is two bits. Not bytes, bits.

and, in my opinion, an incremental backup that does not
handle deleted records is an application specific solution.
If your application never deletes records, the technique
works, but it does not generalize.
