I haven't used it. As with all backup/recovery planning, you need to look
at what your recovery window is, and how you want to get there. Having
several backups of different kinds for mission-critical systems is not a
bad idea.
As I understand it, their basic approach is to automate the base backup/wal
archive method of backing up. I don't think that comparing to pg_dump is
really fair because these are very different backup methods and I think
snapshot backups (i.e. pg_dump) are the way to go for many installations.
You have a larger loss of data, but you also have a much simpler
backup/restore process with less that can go wrong. You can also do the
base backup/wal archive approach by yourself. This buys you point in time
recovery (recovery to just before some idiot dropped acc_trans for example)
but it makes the actual backup/recovery process a bit more complex.
Hope this helps,
