usage: btrfs-image [options] source target
Create or restore a filesystem image (metadata)
Options:
-r restore metadump image
-c value compression level (0 ~ 9)
-t value number of threads (1 ~ 32)
-o don't mess with the chunk tree when restoring
-s sanitize file names, use once to just use garbage, use twice if you want crc collisions
-w walk all trees instead of using extent tree, do this if your extent tree is broken
-m restore for multiple devices
-d also dump data, conflicts with -w
General:
--version print the btrfs-image version, builtin features and exit
--help print this help and exit
In the dump mode, source is the btrfs device and target is the output file (use '-' for stdout).
In the restore mode, source is the dumped image and target is the btrfs device/file.
