Compressing a big folder and wanting progress

gist.sh

sudo su
tar cf - <folder> -P | pv -s $(du -sb <folder> | awk '{print $1}') | gzip > data.tar.gz

# Outputs something like this
# 3.06GiB 0:03:01 [15.8MiB/s] [========>                              ]  5% ETA 0:57:05

# I recently needed to perform a data recovery on a bad migration where I deleted the wrong stuff. I tried to recover data
# from a mysql 5.5 dump to a mysql 5.7 ubuntu 16.04 google cloud box and even though I could edit the data and fix the deleted 
# rows in the tables, I coulnd't export it well enough since incompatibilities between 5.5 and 5.7 :(
#
# I am using this command to copy the fixed data out, so I don't have to redo 2 days of work. I will save the zip somethere
# and restore using a ubuntu 14.04 and mysql 5.5 and try and use that to get the mysql dump .sql file with.

# Extracting side
sudo apt-get install pv # progress bar dependency

pv /path/to/data.tar.gz | tar xzf - -C .
# Outputs something like this
# 3.06GiB 0:03:01 [15.8MiB/s] [========>                              ]  5% ETA 0:57:05

Also don't work in /tmp if you reboot the server you lose your files. :(
