I have found the tools seems to be as good as "dd" for snapshot vxfs filesystem. but the man page does not document the proper restore method. if it can read the vxfs out and stored as a file.
Then it is possible to do "fs-based" (or nearly-raw) backup to a big file and backup the bigfile.
i.e.
to backup
vxassist -g testdg make testlv 10g
mount -F vxfs -o snapof=/dev/vx/dsk/testdg/originallv /dev/vx/dsk/testdg/testlv /mnt
fscat -f /otherfs/bigfile /dev/vx/dsk/testdg/testlv
backup /otherfs/bigfile
to restore
restore bigfile to /otherfs
fscat -f /dev/vx/sdk/testdg/originallv /otherfs/bigfile
possible?
supported?
thanks.
