# Purpose :
# Create an XZ archive of all files between 2 dates.
# Then remove these files

# Call this script from an /var/lib/xymon/hostdata subdirectory or
# /var/lib/xymon/histlogs subdirectory.

# Vars {{{
## Enable (0) or disable (1) debug
debug=0

## Manage files of year
date_year="2019"

## Compress files between these dates
date_start="${date_year}-01-01 00:00:01"
date_end="${date_year}-12-31 23:59:59"

## Best XZ compression level
xz_compression_lvl="-9"
## Fatest XZ compression level
#xz_compression_lvl="-0"

## Get current directory name
current_dir=${PWD##*/}

## Archive name
tar_file_name="${date_year}.${current_dir}${xz_compression_lvl}.tar.xz"

# }}}

[ "${debug}" -eq "0" ] && printf '%b\n' "Create an archive for ${current_dir} files between ${date_start} and ${date_end} using XZ's compression level : ${xz_compression_lvl}."
