I am making backup of a Plesk Debian server to /backup using Rsync.
My questioin is how can I preserve the ctime, mtime, and atime of
original files?
- Preserving the mtime is just rsync's --times (-t) option.
- To preserve the atime, you'll need a copy of rsync containing the
atimes patch:
http://rsync.samba.org/ftp/rsync/patches/atimes.diff
Then use the --atimes option. Unfortunately, this patch makes no effort
to avoid hitting the atimes of the source files; you might want to
either hack do_open in syscall.c to add the O_NOATIME flag or enable the
"noatime" mount option on the source filesystem during the backup.
- Linux filesystems generally don't allow the ctime to be set to a time
other than the current one. I suppose a process running as root could
preserve ctime by repeatedly changing the system clock, but that might
have nasty consequences elsewhere. If you are sure you need to preserve
ctimes, I would recommend doing a block-level copy of the filesystem.
