howto sync two directories

[z_haseeb]

How can i sync two directories (the files in the primary directory might be in use)

Details
i have a directory name DIR-1 on computer-1 and a second directory DIR-2 of computer-2 mounted on the computer-1 which is mounted on computer-1 as /mount/DIR-2

man rsync

If you mounted the directories just for syncing, then you dont have to do that.
Rsync works over the network

Quick and dirty:
On computer-1
rsync -av -e ssh /DIR-1/* USER@computer-2:/DIR-2/

This requires:
- Your current user on computer-1 has access to DIR-1
- USER on computer-2 has access to DIR-2
- ssh is set up
- rsync is installed on both

Notes:
- the -v (verbose) option might or might not be desireable. It will print each file transmitted
- using ssh is a quick and dirty way, but "raw" rsync -ie with an configured rsyncd- is faster, as there is no encryption
- within rsyncd.conf you can also define users/passwords, etc
- Be carefull, what you rsync and where. Especially with --delete

You can use cron to schedule the command. Make sure you are happy that it's workin as you wish, then use crontab -e to edit your cron.

Cron can be quite complicated, it'd be best to read up on it first. Cron.

.---------------- minute (0 - 59) 
|  .------------- hour (0 - 23)
|  |  .---------- day of month (1 - 31)
|  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ... 
|  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7)  OR sun,mon,tue,wed,thu,fri,sat 
|  |  |  |  |
*  *  *  *  *  command to be executed

An example for every five minutes might be

*/5 * * * * rsync -av -e ssh /DIR-1/* user@computer-2:/DIR-2/

You can try to use iFolder. Just search in google.
