RDUP-TR(1) rdup RDUP-TR(1) NAME rdup-tr - transform rdup output SYNOPSIS rdup-tr [OPTION]... DESCRIPTION Transform rdup output into something else. Where something else can be a tar, cpio, pax archive or another rdup stream. The rdup archive must be given on rdup-tr's standard input. You can select multiple types of output (-O flag), but you must be aware that you may loose some information in formats other than rdup's own, see the table below. You may also supply rdup-tr with only a list of pathnames, this can be selected with the -L flag. The following table shows what happens with the output depending on the input. 0 OK D delete information is lost H hardlink information is lost | | output | tar,cpio,pax | rdup input | | ------------- | ------------- | ------ rdup | D | 0 filelist | DH | H | | OPTIONS -L Select list input format. Normally rdup-tr accepts rdup output, with this option you can give it a list of path names. Note: with list input rdup-tr will `stat()` each file, so this can not be used in remote back ups. -O Output format. This can be 'tar', 'cpio', 'pax' or 'rdup'. It defaults to 'rdup'. -X key Read the encryption key from the file key and encrypt all paths with Blowfish and this key and iv. After the encryption the bi- nary data is converted into ASCII using an URL safe (Section 4 of RFC 3548) version of base64 encode. The encryption key must be on the first line and the key size must be 16 and 8 bytes for the iv, so 24 in total. -Y key Read the decryption key from the file key and decrypt all paths with Blowfish and this key. Before the encryption the paths are converted to binary by using an URL safe version of base64 de- code. -c Force output to the tty. Normally rdup-tr wants to see it's out- put redirected. -v Be more verbose. Print the processed file names to standard er- ror. -V Print rdup-tr's version. -h A short help. EXAMPLES The following is possible rdup -P gzip -P "mcrypt -f KEY -c" /dev/null /home | \ rdup-tr -O tar -X<(echo secret) | gzip > \ my-home-zipped-crypted-pathcrypted-tar.gz That is: all files under /home are gzipped and encrypted on a per file basis (first line). Further more, all pathnames are Blowfish encrypted (second line) with the key 'secret'. This is put in a tar file, which is then compressed, resulting in the final output (final line). Creating a compressed and encrypted tar archive out of a full rdup dump might be done as follows rdup -P gzip -P "mcrypt -f KEY -c" /dev/null /home | \ rdup-tr -O tar > my-home-zipped-and-crypted.tar Or even pack and unpack it on the fly rdup -P gzip -P "mcrypt -fKEY -c" /dev/null /home | rdup-tr -Otar | \ ssh user@remotehost tar xvCf /tmp - Or encryption with openssl rdup -P "openssl enc -e -des-cbc -k secret" /dev/null /home Or, compressing with gzip, encrypting with openssl and then compressing the entire archive yet again rdup -P gzip -P "openssl enc -e -des-cbc -k secret" /dev/null /home | \ gzip > my_compressed_encrypted_rdup_archive.gz EXIT CODE rdup-tr return a zero exit code on success, otherwise 1 is returned.
