level 0 backup done with tar 1.18-2 17GB level 1 backup done with tar 1.18-2 2GB level 2 backup done with tar 1.19-2 19GB Can these 3 files be used to restore a system assuming that the newly installed system is using tar 1.19-2? I did something that was probably a dumb idea. I hand edited the snar-2 file (level-2 backups) and changed the version of tar on the first line back to 1.18-2 which had been updated to 1.19-2 during the conversion you mentioned. Have I potentially broken something? I performed a second level 2 backup using the hand edited file that resulted in a full backup. I then performed another level 2 backup by copying snar-1 to snar-2 but it is still saying 1.18-2 in snar-2. Is the conversion a one-time action even if the snar file version header gets changed back to 1.18-2? Is the rest of the snar file still upgraded despite the fact that I have copied snar-1 over the top of the converted snar-2 file? Regards, andrew.
