Copy Methods
Posted: 25 Jun 2005, 23:25
I have been using AllSync for a few days, and the backups are really slow. My needs are as follows: I am backing up a remote site (over VPN) to a local hard drive (let's call it "task X"), and I am also backing up a local drive to a NAS on the local network (let's call it "task Y"), both with copy method B, which is the default for Windows 2000.
I think I could save a lot of time by unchecking the "Overwrite file if the content of the files is different" option. With this option enabled, AllSync must scan each entire file for differences, wasting precious time. If the program doesn't check contents, each file check will take almost no time, no matter how large the file is, unless it actually must be copied.
Is the above theory correct?
Second, your statistics show that copy method B takes significantly longer than the others over a network. I don't want to lose all interactivity, so I don't want to use method A. I also noticed that method C takes longer than the others with a USB stick.
Which method do you recommend (i.e. which is fastest) for "task X", and which for "task Y"?
Assuming you're going to say method C, what settings should I use? Of course no pause, but what would be the optimal data packet size?
Thanks
