Todo List

• Test against large database
  • HXN Backup (~40G) takes around 12-15 minutes being 11 minutes for the mongodump
• Change the comparisson between backups. Maybe md5, sha1 or other.
  • The diff command was taking 1:39 minutes for a ~40G backup.
  • Changed to compare file by file with cmp command and stop on the first difference.
  • New strategy with cmp is faster when files are different but will take ~2 minutes two compare to similar ~40G backups.
• Error Handling
  • Check if the host is reachable
  • Check if mongodump exists
  • Check if user running the script has write permission to the DUMP_PATH
  • Handle execution errors
• Log
