8.7: Builtin Compression

ftape-4.04 introduces a major incompatibility w.r.t. to backup sets written bye ftape-3.04d. The compression support has vanished. See ftape-3.04d's builtin compression (info file ftape). See ftape-3x compatibility.

You still shouldn't use tar -czf ... to produce compressed backup sets as tar compresses the entire archive as a single byte stream; a single clobbered byte at the beginning of the data stream make it almost impossible to recover the remainder of the archive.

Use a more elaborate backup system instead. The

Ftape home page

contains some links.

Note: Decompression of compressed archives written by ftape-3.04d and earlier versions is still supported.
