I’d in general cd to the /opt/observium directory before making the tar and just passing the rrd folder name.

Thank you Ahmed. From what you say I believe its not a problem and the file can be used to restore to another server.

Hi Terry,

The 'tar' command strips the leading '/' to avoid overwriting an existing file in case you extract the archive into another folder.

It only means that if you're backing up a file with it's full path, you need to extract it in the root directory in order to get it back at the same location.

Adding the --absolute-names option will remove the safegard at archive creation.

It actually only makes a difference at extraction time.

HTH,

Ahmed.

The command I am actually using  is tar zcvf /opt/backup/observium-rrd.tar.gz /opt/observium/rrd which I think is why I'm receiving the message.

I am not clear what is rally happening so am not sure if the correct thing is been written into the archive. Perhaps someone can throw some

light on it for me?

When backing up rrd with tar zcvf observium-rrd.tar.gz rrd I get the following message:

tar: Removing leading `/' from member names

Is this OK or should I use the --absolute-names option?

Also I am getting some messages saying file changed as we read it. This is understandable but do i need to do anything while running the backup to stop this from happening?

Thanks in advance.
