How long would a full backup of 900GB of data take using Time Machine?


hi there

how long take backup 900gb of data doing full back-up using timemachine , macbook? macbook being 2009 model 2.13 ghz intel core 2 duo , 4gb 800 mhz ddr2 sdram.

have:
1 x macbook 160gb drive
1 x imoega minimax 500gb drive (firewire or usb 2 connection possible)
1 x seagate 320gb drive (usb 2 connection)

have 400 firewire port in macbook in addition 2 usb sockets, firewire hub power supply, should wish run 2 or more firewire devices @ once, 400 firewire port.

current backup drive samsung usb2 1tb drive reasons become obvious below, need purchase new drive. think 1.5tb or 2tb fine , guess 400 firewire port still better usb2, though it's 400. i'm not sure time issue.

need run regular full backups incremental or differential backups not vast. don't wish have computer in-accessible long periods of time because has run full up. can run backups @ night on old pc take 14 hours or more , 500gb of data being backed up. had through forums couldn't find on time taken backing up. explain reasons asking this. warning else doing similar.

had mft [master file table] , mft mirror corrupt on iomega 500gb hard drive. think boot sector still working , run tests later on. drive formatted ntfs, until pc only.

had been running backup system backed 1tb samsung usb2 hard drive. system used based on creating incremental backups full quite sometime in past. way saved on disc space , run backup system longer before had restart again. using windows based cobian backup black moon job because free , worked recovering occasionaly accidentally deleted or corrupt file.

need put whole system state before failure , have hit problem. have lots of incremental backups , none of linked together. restoring each incremental in date order, may end files, changed name, existing under previous name or files deleted being added. result in duplication.

piece of software, getdataback, can recover files i've run demo of , showed file system. able view contents files, e.g. viewing photos. whilst restoring now, isn't long term solution , need create full backups more regularly. why wondering how long take.

kings regards
