From: Andrew Tridgell <Andrew.Tridgell@anu.edu.au> To: Subject: First release of rsync - rcp replacement Date: Wed, 19 Jun 1996 03:12:30 GMT -----BEGIN PGP SIGNED MESSAGE----- Paul Mackerras and myself have just released a package called rsync on ftp://samba.anu.edu.au/pub/rsync rsync is a rcp replacement with some special features: - - it uses a special remote update algorithm that allows it to send just the differences between the source and destination files if the destination file already exists. It can do this without requiring that both sets of files are available on one end of the link. This makes rsync very fast when updating over a slow link. A tech report on the algorithm to do this is included in the package. - - it uses rsh or ssh for communications. It requires no special privilages to install. - - it has many options found in GNU tar and GNU cp, such as copying links, devices, permissions, times, ownership etc - - it has the --exclude and --exclude-from options from GNU tar - - it has a --cvs-exclude option to tell it to ignore the same files that CVS would ignore - - it uses a pipelining technique which overlaps communication with computation and removes the latency cost for each file - - it is only a week old and therefore probably has lots of bugs :-) Enjoy! - -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Andrew Tridgell Dept. of Computer Science email: Andrew.Tridgell@anu.edu.au Australian National University Phone: (06) 254 8209 or (06) 249 5691 Fax: (06) 249 0010 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- -----BEGIN PGP SIGNATURE----- Version: 2.6.2i iQCVAwUBMcdv2oQRll5MupLRAQHzlAP/ZXhZuowXi5MvpT4O2swucz590cAM4k/K EMQY06R6E44RZb2l0sPeje/Ja/MvbjOWywzqtx7pvaNe3eA0Qxi5KHuIK7HHdZu7 Z3YysZGg9pF5UQyu0cUG0mXzxXZBLN6//wIPFUutGuMU0UifghQCkEHrKwziNdU/ TVal4tQ2hI0= =RPo2 -----END PGP SIGNATURE----- -- This article has been digitally signed by the moderator, using PGP.
