I'm still confused about this. Is it because the kernel buffer vs page cache architecture is inherently flawed, implemented poorly, or is ext2/3 dump the problem? Since xfsdump and XFS are not subject to the same caveats, it would seem possible to write a dump util for a filesystem in the 2.4.x kernels which works subject to the usual limitations of dump on a live filesystem. Linus does mention in the above: However, it may be that in the long run it would be advantageous to have a "filesystem maintenance interface" for doing things like backups and defragmentation.. Is such an interface necessary? I doubt FAT16/32 has such an interface, perhaps it is so simple it doesn't require one. Syncsoft's backup util for Windows NT/2000 claims it can backup live filesystems without file corruption - does NTFS have such an API? -- C.
