rsync - Nov 2012 - Rsync --update copy one file multiples times

Hi All,

My using rsync command to backup my mail server mailbox to backup server.

I am using following command for backup.

rsync  -avzu -e ssh root at 192.168.1.12:/mail_home  /mail_backup

I configured daily cron for this command in backup server.

In mail server /mail_home folder having all user's mailbox and size of 
mail_home is 345 GB and in backup server I have assign 450 GB for 
mail_backup drive.  when I run command first time its copied all mailbox 
folder from mail server to backup server but when crontab run second 
time in backup server the Mail_backup drive showing full. after that I 
run script on backup server and mail server which show all folder size 
and compare with both results. in both server each folders size is same.

Now I am wondering why backup server showing  Mail_backup full.

That lets 105 GB of free space for the temporary copy done by default
for each file.

I suspect there exist a file (a mail folder in your case) of size
greater than 105 GB. That seems huge however for a mail folder.

Try to add the --inplace option to your rsync command. This option is
appropriate for backing up mail folders (as far as I know).

This is weird: if the filesystem became full during the second rsync,
rsync should have failed.

Are you sure the filesystem became full?
