Fer asks: "Are there backup program for Linux that do not have filesystem or volume size limits? I am trying to make a full backup of a 22 GB FTP server, using 4 GB TR-4 tapes. I have tried tar, dump, afio, taper, and afbackup, and every one of them either did not allow >2GB volumes or had weird problems with >4GB filesystems. Currently I am using dd to do the job, but I think there must be another option. Any suggestions on free programs which I may use?"
