So we have had a used 2011 macbook pro 17 inch. It was very fast the first day we had it i mean fast like no beach balls, almost ssd performance(750gb hdd). anyways the next day or 3 days later we had the spinning balls and feels less responsive/ much slower than before should i defrag(someone said thats only for windows) i did a os update and reinstalled. Also does anyone know of any FREE data recovery tools as i lost my microsoft word in the os reinstall to mavericks.

An OSX re-install will not change any settings or remove any programs, so it's pretty much a zero risk operation and should hopefully fix any issues.

Under Disk Utilities, you can also Verify Disk and Verify Permissions. If they show any errors you can repair from there. This sometimes fixes little problems.

As for backup, the built in Time Machine software is excellent.

The only back up system for mac is time machine, but it's not very good. Remember that if the Hard drive you use for your backup becomes full... time machine will stop working... it's horrible when you want to find something just to realize your time machine stopped working 2 months ago!

That is incorrect. As Apple say:

As your backup drive begins to fill up to its capacity, Time Machine intelligently deletes the oldest backups to make room for newer ones.

Time Machine is a superb backup system.

We all know that even if apple says it does that it doesn't mean that's what actually happens.

I have 4 machines here at work on time machine and 3 have stopped working for that reason.

Time machine is VERY UNRELIABLE. Use at your own risk.

You may get (apparently) this problem if you haven't specified the size of the backup disk correctly and/or if you backup several machines (or users) to the same disk. No backup program can cope with an inappropriate setup.

Annecdotal evidence proves very little, but I have used Time Machine on several machines for several years without a problem. (I've also used backup programs since the year dot on everything from the original IBM PC to mainframes. Time Machine is about as good as it gets - not as good as Tivoli Storage Manager with a dedicated server and automated tape library, but not many home users can afford that.)

Anyway, as you state that TM is the only backup program available for Macs (it isn't) what do you suggest as the alternative - don't do any backups?

What I suggest is if you work in an office. The server should have a real back up system. As for your computer you can use time machine, but dont expect too much of it.

Not QUITE.

Time Machine keeps:
-Hourly backups for the past 24 hours
-Daily backups for the past month
-Weekly backups for all previous months

The oldest backups are deleted when your disk becomes full.

In my 5 odd years of using it for ~ a dozen computers across 3 locations, it's always been great.

As said, I found the software to be great.
Backups happen automatically in the background, and restoring files via a visual interface is a bit of magic, especially coming from windows.


Apple's Time Capsule hardware has been 50/50.
I had one of the previous 1Tb models, which i DIY'd to 2Tb after ~18 months.
After ~3 years 24x7 usage, Wifi etc slowed to a crawl. After much searching I found the internal power supply was a rubbish design, and would eventually fail. The repair was to solder an extra capacitor to smooth out power delivery.
I tried this, but It didn't work.

I was pretty annoyed since they aren't cheap, and everything else Apple has lasted a long time.
Still, 3 years of 24x7 usage is a good life in a business environment for a consumer level product.
