There are a number of defenses you can use to help prevent and recover from theft.
The first thing you should look into is full-disk encryption, e.g. LUKS, TrueCrypt, or PGP. This will prevent an attacker from reading any data on the disk, even if they steal the hardware. You will need to enter the password at boot, though, so for unattended remote hardware ...

Going by your threat model which is theft of the server, I would choose to go with full disk encryption in the form of LUKS or similar.
For that threat model though, encryption shouldn't be your focus. Instead, make sure your datacentre has appropriate physical security in the form of access control, surveillance and the likes.

As mentioned rar uses SHA-1 which is pretty strong. You can have a good comparison of different algorithms here.
As you can see cracking rar is slower than WPA-PSK.

There is some data here. WinRAR uses a custom key derivation function which involves thousands of SHA-1 invocations. Apparently, with two good GPU, about 15000 passwords per second can be tried.
Then it depends, not on the length of your password, but on the way you produced it. It's not the length which makes the password strong, but the randomness. If ...

The answer is 42 of course.
In all seriousness, this question is unanswerable. There are many factors, including but not limited to the amount of hardware the attacker is willing to throw at you.
Your password is weak though, it's very predictable which is the bane of strong passwords.
