One of those is to use dump(8), assuming you are using UFS filesystems, of course. Make regular dumps (of different levels), compress them using bzip2(1), encrypt the compressed dumpfiles using openssl(1) (do _not_ use crypt(1)!) and use ftp(1) to transfer them to the hosting company. Another way is to use mtree(8). You can use this to generate a file contain= ing the state of a filesystem hierarchy. Running it against a previously saved specification can yield a list of files that have changed. Use tar and bzip2 to create an archive of the files that have changed. Encrypt and send same = as above.=20 All these programs come with the base system, you would just need to script them.
