    Yep... depending on the computer it might seem a little slow, though.

    RE: TM requirements...

    Hi \-V-/,

    Once TM has done its initial backup and Spotlight has indexed all of the disks, then TM should not be much of a drain on the computer's resources. This is because the index allows TM to backup just what has been changed since its last backup without TM needing to "search the entire disk" for what to backup. TM only refers to the index to know what files need backing up, and thus this requires very little computer resources.

    In other words, once TM and Spotlight are "up and running", so to speak, there will be a minimal impact on the computer's resources and speed when doing TM backups. Of course, the TM backups, if done wirelessly, do take up some wireless bandwidth, and this you might notice, but since most hourly TM backups are minimal in size (they are differential, not full, backups) the amount of data transferred wirelessly is quite small and so shouldn't have much of an impact on your wireless either.

    Just thought you would like to know...

    I don't understand how people can assume and then spit out several paragraphs based on one sentence.

    During the backup process... yes... it will be a little sluggish. Once it's done... it won't be sluggish anymore. The amount of sluggishness depends entirely on the computer... and it isn't noticeable whatsoever on an SSD.

    I wouldn't but that's just me. I just let Time Machine do it's thing.

    If I need to use it, I'll back up overnight.

    maybe you should read the whitepaper on Time Machine so that you don't get pissed when someone else elaborates for you.

    to add to what was said and maybe to affirm your "theory", it depends on the amount of changes being tracked fseventsd. so if you haven't done anything but browse macrumors site, there shouldn't much to backup. but if you have imported a boat-load of movies/pics/or-what-have-you, of course, there is latency due to disks and SSD doesn't change the process, just makes it faster.

    so yes, uninformed people's opinions have to be elaborated for the sake of others and not you. :mad:
