I am in the process of installing 11.2 (X86-64). By default the root partition was formatted as ext4. I am also thinking of possibly using raid 1 for some partitions (disks). While doing some research for this I discovered an item that stated the dump package (dump restore) does not support ext4 and worse may appear to dump but not be able to restore. I can’t seem to find any reference to this in the openSUSE documentation. This has seriously broken my backup system.
I currently backup to external hard disks with a mixture of full backups of all partitions and incrementals. After a new full backup the old incrementals are deleted. In effect I keep 4 weekly full backups and then 1 in 4 or 5 to give monthly backups going back about 6 months.
Has anyone got any idea how this can be done with ext4 or should i move to another file system.
I have had a quick look at DAR but can’t find anything that about support for ext4. There seems to be people using rsync but that really isn’t a backup system. I think you would still need to backup an ext4 partition even if it was the rsync target and the restore is likely to be horribly complicated.
I do not particularly want to use partition cloning as this normally requires that you boot into another system to copy the partitions and it is often difficult or impossible to extract individual files.
