BackupChecks

This python script can help you to check if your backups are OK. You can chech if you have recent backups, if they have a correct size, e.a.

Here you have some examples to know how to use.

I will use this as post-scritp in Elkarbackup: https://github.com/elkarbackup/elkarbackup

In backupfilecontrol.py you have to change the values of EMAIL_FROM and EMAIL_TO variables, and in the sendmail.py you have to change the value of DEFAULT_SMTP variable.

minimum_size = 50 
maximum_days = 5   # If the file would have more than 5 days, it would be to old
recursive = False 
path = "/media/Backups/elkarbackup/0003/0012/Daily.0/home"
myfolder = BackupFolder(path, [{'extension':".bak",'include_text_in_name':'MYDB','maximum_days':maximum_days, 'minimum_size_mb':minimum_size}], recursive)
myfolder = BackupFolder(path, [{'extension':".bak",'maximum_days':maximum_days, 'minimum_size_mb':minimum_size}], recursive)
myfolder = BackupFolder(path, [{'extension':".bz2", 'minimum_size':50, 'minimum_files_number':2 }, {'extension':".bak", 'minimum_size':150, 'include_text_in_name':'MYDB'}], recursive)
myfolder.check_folder()

path: is the path of the folder that we want to check

check_extensions: is a list of dictionaries, whereas each dictionary gives information about the validation to make for files of one expecific extension. The keys of the dictionary may be:

  • extension: the extension to check

  • maximum_days: if one file is older than this value (in days), it would be considered as error. Default 10 days

  • minimum_size_mb: if one file is smaller than this vale, it would be considered as error. Default 5MB

  • minimum_files_number: There may exists at least this number of files for this extension. Otherwise, it would be considerer as error. Default 1 file

  • include_text_in_name: By default not checked. You can use this if you want only check files that have some test in their name. recursive_check: if true, the check will be done recursively

This is an example of a python post-script to use with Elkarbackup

#!/usr/bin/python

import sys
import os, os.path

sys.path.append('/root/scripts/python/backupchecks')

from backupfilecontrol import BackupFile, BackupFolder

ELKARBACKUP_PATH =  os.environ.get('ELKARBACKUP_PATH')
PATH = ELKARBACKUP_PATH+"/Daily.0"
RECURSIVE = False

myfolder = BackupFolder(PATH, [{'extension':".bak",'include_text_in_name':'SAGE','maximum_days':5, 'minimum_size_mb':2500}], RECURSIVE)

myfolder.check_folder()
