comment Pass your password to your SSH key via a script
The alternative you're proposing is providing a method of getting the encrypted key and password to decrypt it from the filesystem. I can't readily imagine a circumstance in which this is less secure than the unencrypted key being held within a program's memory.

comment Backing up a MySQL database - while it is still in use
I would define "sufficiently large" as a hunch. If your database backs up fast enough with this method and causes no issues for you, go with it. "Fast enough" is up to you. So far, it has been doable for you to fully take the site offline for backups, so I imagine this will be a rather quick process. I would change over if it was taking the better part of the day, causing a load which the database can't keep up with (only likely with deletions), or if I were really bored.

comment Bad disks in ancient server
I want to put this in perspective (that you may already know): Your ENTIRE operation relies on one 12 year old machine that you can't replace for a full year. You have a problem.

comment How do I rsync an entire folder based on the existence of a specific file type in that folder
Every time an AVI file is found, rsync is executed on the working directory... So the first time it finds one, it syncs, and then the other 10,000 times rsync runs again...

comment Setting up a network e-mail server
I find the following often happens: "It needs to be Solaris / HPUX / Linux / etc." -- they have a solid reason. "It needs to be Windows" -- "well, because..."

Seems that he's saying the MS SQL system is too expensive, so won't be implemented, and he's looking for an alternative?
