New Time Capsule, using Time machine, Macbook pro maverick, problems

Hi there,

Here in the UK just had a message flash up saying something like new backup file has to be created after verification of something or other it now seems to have wiped my original backup of my macbook pro and started a new back up, what is happening. This is the new 3TB Time Capsule running 7.7.2. On my Macbook Time Machine it is showing 3TB available space in Air Port utility it is only showing 2.7TB of space any ideas of what is wrong here?

Many thanks, Tim.

MacBooks, iPhone, Mac OS X (10.6.5), Windows 7 PC's

Time Machine has created a new set of backups, so you cannot access to your old backups. However, they are still there. To restore files from them > http://pondini.org/TM/E3.html

Hi there,

Right at this moment I can do nothing as it is in the process of backing up 323 GB which is really annoying this is a brand new TC and I have been using it for two weeks and now have my MacBook out of action for 11 hours good job its near bed time here in the UK.

Nor does it answer why on the MacBook TM it shows 3TB available yet in the Airport utility it shows only 2.7TB available how much space should I have free on the all new 3TB TC drive?

I do hope at the end of this new backup I can access all my older files?

Many thanks for your quick replies, Tim

A 3TB drive is a trick number.. used by all hard disk manufacturers to make their hard disks look bigger.

3TB is digital bytes.. ie 1000KiloByte in one MegaByte.

In reality bytes are binary.. and there is 1024KB in a MB.

Hence when you format a drive.. 3TB becomes 2.7TB.. that is confusing but caused by lies told by all salesmen.

Sometimes it can be the usage as well is not showing correctly in one or the other.. but 2.7 is the full formatted capacity of a 3TB drive.

Hi there,

Thanks for that I was aware but the issue is my MBP TM is now saying 2.97 of 3TB available yet the Airport utility is being acurate in saying the drive is 2.7TB available so something is going on with the MBP and the TM application and of course it has now done 29.42GB of backup over ethrenet and has 14 hours to go, madening to say the least almost as bad as my PC server backup system.

Again thanks for all the replies.

Tim.

2.97TB is not possible in binary bytes.. the drive only started with 2.7TB.. it is just different ways of looking at the same disk.

Mavericks though could have messed this up.

On Mountain lion I do show the correct sizes if you think digital bytes are correct.

TC says 2TB.. well it is nominally a 2TB drive but it formats to 1.8TB..

In airport utility.. 5.6 version it show it correctly in binary bytes.

In the new airport utility it has gone back to digital bytes.

Anyway.. that is hardly an issue.. it is software being inconsistent.. which is no surprise.

it has now done 29.42GB of backup over ethrenet and has 14 hours to go, madening to say the least almost as bad as my PC server backup system.

Again thanks for all the replies.

Force it to ethernet only.. you should achieve 50-60GB per hour on TM backups.. average.. it can be slow in the middle with lots of small system files.

Turn off wireless in the computer to ensure it is using ethernet only. Many times if you have both wireless and ethernet connected even with wireless under ethernet in the priority of interface, it will still slow the ethernet.

Hi there,

FIrstly I am using ethernet even though it is the all new TC, backing up this ammount over wireless would take even longer and still we have not finished.

So just to show you it is showing 3TB whereas AU is showing Capacity 2.7TB available 2.4Tb used 319.2GB, User 1.

All I can say is bizare.

Many thanks, Tim.
