[QUOTE="bobtomay, post: 761934, member: 24160"] Only the initial Time Machine back up does a full backup. Every additional backup is an incremental back up. That is, it only backs up those files that have changed or been added since the last back up. It keeps hourly backups for the past 24 hours. It keeps daily backups for the past 30 days. It keeps weekly backups for everything older than 30 days. Any file that was backed up during any of the hourly backups will be available long term. Time Machine will not delete any of your old files until such time as the drive is full and it has to delete the oldest in order to make room for the newest. That is, you will have an archive of every file that has been on your computer until that time when Time Machine begins erasing the oldest data to make room for the new. To make a guestimate of when that might be, take a look at how much used and free space you have on the back up drive. I have seen no reason to not allow Time Machine to run full time. And I am connecting from a MBP to a Time Capsule wirelessly. I have noticed no sluggishness it has caused to any application, including playing WoW for hours at a time over that same wireless connection. Have only been using Time Machine now since the middle of August. I currently have 87GB of data on the drive being backed up and through the course of TM being on for 4 months, the backup is only taking up 135GB of my 1TB drive. If you would like to be doubly safe, you could get another external drive and create 2 partitions. On one partition, use SuperDuper and create a bootable backup of your internal drive. That way if your internal dies, you merely reboot to this backup and keep going as if nothing (much) happened (as long as you keep it up to date). Use the other partition for archival purposes. Between this and TM, you would then have two places to hunt down any files you may have deleted and decide later you want back. (At least you would if you copied them to this archival partition, prior to deleting them.) [/QUOTE]
