rsync - Aug 2010 - backup option

Hi,

I am using rsync to backup files. Is it possible to specify an option
not to delete files from backup directory if the files are deleted
from source? In that way, I can always keep something I may or may not
need in the backup disk, but remove it from a work computer.

Thank you.

Kind Regards.

Would that not be done by omitting the --delete option?

As Alex mentioned the omitting the --delete option is the way to go. 

However, you should keep in mind that (depending upon the rsync options you
provide) if you update a file (within the source directory) the then older
version of this file in the destination directory will be overwritten.

If you want to preserve old revisions of files, there are various rsync options
which will allow various actions to be take place to the older versions which
already exist in the destination directory.

Below is an example of what I am talking about with regards older versions being
overwritten in the destination directory when using the --archive rsync option.

> $ rsync -a 1 2
> $ cd 2/1
> $ ls -a
> .     ..    hello
> $ cat hello 
> hello there

You will notice that there is no copy of the original (blank) file only the more
recent version which contains the "hello there" text.

If you check the rsync manual page and perform some www searches, you will find
many options and approaches relating to what happens to updated
files/directories when you run rsync.

Perhaps you want the --backup --backup-dir=DIR options?

        -b, --backup                make backups (see --suffix &
--backup-dir)
            --backup-dir=DIR        make backups into hierarchy based in DIR

Thanks all responses. That works fine.

Kind Regards,
