My future plan for when my database grows larger, is with the use
of WAL logging – have a base backup taken on a Sunday morning (our
quietest time), ship this to the hot-standby once a week, and start
it off in a recovery mode (using my rolling-WAL script I’m testing
now.) Then throughout the week, send the WAL logs from the live
box as they become available down to the standby, which then get
processed on arrival – these files are 16MB in size (I believe this
can be changed).
Theoretically the size of WAL files can be changed, but in practice
no one ever does this. In other words, it's probably not a great idea.
This is coming from an 8.1 server, I believe it’d be okay for 7.4
but don’t quote me on it.
PITR was introduced in 8.0. There's a number of other reasons to
upgrade as well. In the meantime, Slony might be a viable alternative.
