Time Machine is taking so long to backup!

[petrucci666]

2011 13" MBA here with 128GB of space. The actual backup file is about 75GB and I initiated the backup an hour ago. It has only backed up 12GB so far.

The backup disk is a 1TB WD My Passport if that matters.

It is being painfully slow and I don't know why!


Any thoughts?

Just by what I went through this morning, that is fast. My 2011 MBP took well over three hours to backup 5GB.

Is this the first time you've used this HDD to run backup? Usually the first time takes a while. After that it will normally take only a few minutes depending on how much data has changed between backups.

How are you connected to the backup device?

It was my first time, so I can see why mine took long.

The initial backup should be done via ethernet. It will take a couple of hours and then you can switch to wi-fi for subsequent backups.

Just backed up 75GB last night and it took about 3 hours.
