.... Say I record the transaction ID of the last transaction to be backed up each night, pack the database, then with my next backup, only back up transactions with an ID above that. Is there any reason why this wouldn't work as a strategy?
Not sure I really want to be responsible for a completely custom backup strategy, but I would like to know a bit more...
Packing can change old transactions (by deleting no longer used object records). Also note that a FileStorage contains back references (references from one object record to a previous object record). Such back references make it difficult to sticht together a backup for transactions until a given tid and one for transaction from this tid onward -- when some packing has happened in between. -- Dieter
