moving form to a new server/webhost

[webspawner]

I cd to the htdocs and type in:

[domainXXXXXX@ssh-server htdocs]$ tar -cjfp sitebackup.bz2 /full/path/to/folder/htdocs
tar: sitebackup.bz2: Cannot stat: No such file or directory
tar: Removing leading `/' from member names
tar: /full/path/to/folder/htdocs/p: file changed as we read it
tar: Error exit delayed from previous errors

Any idea's why this is happening :S

could I try anything else?

I have my database backed up (and did that via ssh- im not a noob with it but unsure what to try next)

any idea?s

thanks

PS: also when i do the command:

tar -cjfp backup.bz2

It returns as though it has been successful and when I check files in htdocs it is there but at 0kb
