I run three levels of incremental backups using 3 different snar files. I upgraded to a newer version of my distro that has tar 1.19 and now my level 1 and level 2 incrementals do not work anymore, instead they do a full level 0 backup.
I have performed an incremental restore with my backups after having wiped my disc and installed the newer distro, which worked perfectly. I had restored my snar files under /var/log/backups and they had retained their creation dates, as have my files under /home (the directory i backup). The previous version of tar on the old distro version was 1.18. Is my assumption correct that tar cannot use snar files from previous versions of tar? Why not? It is a bit annoying that I cannot keep my backup scheme, and must create new backup sets. regards, andrew.
