Windows 7 Backup
hey, i hope you can help me...
i switched to windows 7 directly from xp, so i skipped vista and am now for the first time equipped with a build-in backup utility.
which i am using regularly. i've got roundabout 250gb of data to be backed up, audio, video, pictures and books, most of which don't change much. the first backup session (on may 7th) to my external usb-harddrive took nearly 24h; pretty long, but i guessed for the first time ok. the next few backups were pretty fast, only around 20 mins, since i didn't change much of my data.
but: sice may 18th, every time i start backup it takes forever, and when i abort it and look into the details, it started a completely new backup. i do have no idea why this happened, but is there any way i can get it to just update the older backup files? i don't see the necessity to let my computer and my external harddrive run for multiple hours...
