rsync files with mtime

[Richard Z]

Hi,

I try to rsync files only X days old.

This is my setup. The backup server needs to store all servers' backup
and only has space for 7 days backup. But each individual server has
backup for 21 days. On the backup server, i remove files older than 7
days. When backup server pulls files, I want rsync only pull files
with mtime last 7 days.

Searching through the archive, someone suggested using

(cd src && find . -atime +6 -print) | rsync --files-from=- src/ dest/

This works on the source server, but not on the dest server.

Anyone knows how to get the job done on the backup server?

Thanks,
