    I have been using a 1TB drive to backup my MBP for almost a year. The drive is going to be filled up soon. What is the best action in this case? Buy another 1TB drive, get a 2TB drive and move existing backups to the new drive or simply remove old backups from the current drive when TM prompts me to? Is it a good idea to remove old TM backups? I suppose that if I delete too many incremental backups, I may not be able to recover some files when I need them in the future.

    I think that TM will keep going over the oldest data you have on your backup once it is full.

    Unless your boot disk is getting more full than the capacity of the TM disk there's no reason to move to a larger disk. I recommend having at least 40GB more on the Time Machine disk than the volume it's backing up.

    Do nothing. Time Machine will overwrite your oldest data and the Time Machine disk will stay around 100% used now until you stop using it. Would you ever need to go back that far?

    yup. Remember, Time Machine is for backing up, not archiving.
