This is a useful command to backup an sd card with relative total size for piping to pv with a progressbar
There are 2 alternatives - vote for the best!
This command utilizes 'pv' to show dd's progress.
Notes on use with dd:
-- dd block size (bs=...) is a widely debated command-line switch and should usually be between 1024 and 4096. You won't see much performance improvements beyond 4096, but regardless of the block size, dd will transfer every bit of data.
-- pv's switch, '-s' should be as close to the size of the data source as possible.
-- dd's out file, 'of=...' can be anything as the data within that file are the same regardless of the filename / extension.
Will automatically take the size of the file but longer, usefull only if in an function.
