All applications slow down your computer however you will not notice a speed difference when the time machine is backing up your Mac.

No. Once you reconnect your external drive to your Macbook Air the time machine backup will start automatically

Do I need to get an Apple-compatible hard drive to work with Time Machine?

Honestly, all hard drives are compatible with Apple Computers. The dive will need to be reformatted. Lucky for you Time Machine will offer to do this for you when you first set it up.

How big does my hard drive need to be for a Time Machine backup?

I recommend at least twice the size of the internal drive of your computer. For current MacBook Airs and MacBook Pros this should not be a problem … Overall Bigger the external hard drive the better.

Yes you can have more than one backup stored on the same hard drive. However make sure it is a big one! Also do not forget to back up all your computers.

I recommend not going into any database files as they are not meant for us humans to directly understand. However if you “Enter Time Machine” through the App it will make a lot more sense to you.

Do I have to backup everything?

No you do not! I have some folders on my mac excluded from the backups because they take up a lot of space and I do not care if they get wiped. (Video samples Etc)

Can Time Machine backup to an SSD?

Yes but I do not recommend this! SSDs have a limited amount of times you can write to the disk. The problem with that is that Time Machine backups will do a lot of rewriting and drastically reduce the life of the drive. If you are looking at making the backups faster you need to consider backing up more often. Because I back up every day my backups take less than a few minutes.
