Thank you very much for the info. Given the situation then, how would
you recommend doing what I'm trying to do? Or what would be a good
method of doing these online backups?

Would doing 1 base backup a day, keeping a couple of days worth, and
backing up the archive logs as the come in be the best way? I guess I
was just trying to do the base and WAL backup at the same time and all
at once, which is probably not what it's designed for, as I'm not
figuring out.

Thanks!
