Currently I am backing up gigabytes and gigabytes of data from a live server to a backup server using an rsync/ssh combination script, allowing for automated operation every night with a cron job.
The problem I am having is with permissions.
Running rsync with -a mode copies over the user:group and filemode, which are currently 54122:games and -rwx--S---.
In order to be able to execute the files on the backup server (don't ask me why the employer requires this), I've had to run a time- and cpu-costly (because of the sheer amount of data transferred) chown() and chmod() setting every file/folder to www-data:www-data and permissions of 755.
Is there anyway I can setup rsync to forcibly set each file/folder to www-data:www-data and 755 or am I looking at this problem from the wrong angle?
I guess I could run -rltD instead of -a (which is equivalent to -rlptgoD) but then what happens to new files? What permissions and owner:group settings do they receive?
