Cron rsync command question

[williammanda]

I have setup rsync to backup a drive everyday using cron. This is the command:

0 1 * * * /usr/bin/rsync -av --stats --delete /media/sdc1/ /media/sdd1/

My understanding is that the "--delete" will delete any files on the backup drive that are not on the source drive....but it doesn't. The backup drive has accumulated all the files that were deleted on the source drive. If the rync command is correct then why are the files not being deleted or if the rsync command is incorrect please supply the correct command.
Thanks

The cron was setup as a user not root.

anyone?

Are the source and destination mounted partitions or devices?
What kind of filesystem do they have?

I would recommend using the log options to check for details:

rsync  -av  --log-file=/path/to/log/file

Are the source and destination mounted partitions or devices?

Yes they are mounted...I'm not sure I could use them if they weren't mounted. Also they are devices...harddrives...sdc1 and sdd1

What kind of filesystem do they have?

ext4

I would recommend using the log options to check for details:

rsync  -av  --log-file=/path/to/log/file

Regards.

What details am I looking for?

Getting back to my original question....is the "--delete" correctly being used or not?

What details am I looking for?

What files are being transfer, what is being deleted, error messages from transfers and deletions.

This could bring to light some permission errors, links, other partitions under it, etc.

Getting back to my original question....is the "--delete" correctly being used or not?

Yes. That is the purpose of that option: to make an exact copy of the source.

Regards.
