sync folders

guna_pmk · 04-06-2012, 05:33 AM

Hello,

I have a requirement to have two folders in sync. The source is online and the destination is local. I am using Fedora16.

Currently I have added

rsync --recursive --delete source dest

to the /etc/rc.local. Is this the right way or is there any better efficient way to perform this?

Thanks

To add to the above, why rsync takes forever even on fairly identical directories? My source is about 5G. When I first did my rsync it took about 20 min to perform. But it takes the same amount of time every time I do this. Am I missing something?

Thanks

Yes. You have to preserve the modification time to avoid rsync makes the synchronization again and again over the same files. The option to preserve timestamp is -t, but a more convenient way is by means of -a, that is a short way to specify multiple options (-a is equal to -rlptgoD, see rsync --help for a brief description of each option).

Code:

rsync -a --delete source dest

Thanks colucix. I did not want the owner and group of the destination modified. But the -t option certainly helped. Thanks.

BTW the original question is still open. Is this is the right way of doing this? I am looking for something like Windows' 'available offline' option.

Thanks
