hi,
i asked in there too:
http://serverfault.com/questions/263342/untar-selected-files-in-tar-gz-file-from-remote-ftp-server
I will backup virtualmin on a remote ftp server weekly. Lets say i need to get a folder from it but backup file is so big. Is there any way to random access to virtualmin backups from remote ftp server without download it?
maybe UnZip’s random-access operation ?
