How much traffic/cpu load must i expect with my 1TB imac disc for 1TB TC

Question

hi
i want to buy 1TB TCapsule.
my concern is:
i have round 600MB occupied on my internal imac 24" 2,8 disc
and i work with huge image data day per day (200-800MB changing per day)
must i expect very high cpu load when backup/timemachine is running in background
constantly? is it advisable to buy this 1TB TC for my backup-timemachine-purpose?
i presume that the first initial backup would take very long via air? (550MB backup to TC)
maybe 1 week or so? or i could simply do this first backup via ethernet cable?
thanks!!

Did you mean 600 GB rather than 600 MB ?

CPU load will not be that noticeable IMO. With daily churn rate of 200-800 MB you will be just fine. After 48 hrs TM will reconcile the hourly snapshots when creating its daily snapshot and only keep last revision of file(s). The 1 TB TC should work well for meeting your requirement(s).

First TM backup/snapshot will always take a fair amount of time no matter. Again, you specified 550 MB which is a SMALL amount of data. If you meant 550 TB then that's a LOT of data and will take some time to backup up. Using say 7 MB/sec for WiFi then you can transfer 420 MB per min and thus in a perfect world the 550 GB will take 1310 minutes or some 22 hours. Using ethernet should reduce this transfer time considerable and will ultimately depend on the sustained TC's disk i/o rate.
