It can create a cpio format archive, but includes more advanced options such as the -Z option that compresses each file that makes up the archive, and support for files larger than 2GB.

For instance, some programs create their sockets when started, and remove them when stopped. Some of them do not allow to choose the socket permissions, which requires to modify their init script to set the permissions you want after they started, for instance to allow your mail server to talk to your milter. Edit: according to unix(7), sockets must indeed be unlinked when they are not used. Too bad, but indeed, archiving sockets is then useless. I wonder if this is a requirement, and if it is impossible to reuse an unused socket.

When you restore the socket, nothing will be bound to it, and it will have to be unlinked for anything to bind() that path again Sat, 21 May 2011 05:26:00 +0000 Buck https://tanguy.ortolo.eu/blog/article6/cpio-tar/#c1305935581-1 https://tanguy.ortolo.eu/blog/article6/cpio-tar/#c1305935581-1 Don't forget incremental with GNU tar =) Tar also can skip over a corrupted file Fri, 20 May 2011 23:53:00 +0000 Justin Rovang
