Usage

Import

from  mongogbackup import MongoConfig, MongoGBackup

Initialization

mongo_config = MongoConfig(
                                db_name='your_db',
                                host='localhost',
                                port=27017,
                                # optional parameters below
                                username='root',
                                password='password',
                                auth_db='admin'
                            )
backup_handler =MongoGBackup(
                            mongoConfig=mongo_config,
                            credentials_file='path/credentials.json',  
                            key='fernet_key'
                        )
gdrive = GoogleDriveHandler(
                             credentials_file='path/credentials.json',
                             parent_id = target_folder_id,
                             file_name = name_of_the_file_you_want_to_upload,
                             num_files = how_many_files_you_want_to_keep_in_the_rotating_file_handler               
)

Creating dump

backup_handler.backups.backup(dir='backup_path/dump/')

Compressing the dump

backup_handler.targz.pack(source_path='backup_path/dump/', output_path='filename.tar.gz')

Encrypting the dump

backup_handler.encrypt.encrypt_file('filename.tar.gz', 'destination.file')

Uploading to Google Drive

Add your credentials.json file to your project (you can generate this on Google Cloud Console)

Simple upload to google drive

gdrive.upload_file_to_drive(file_name, parent_id)

Delete all previous files with same name and upload to Google Drive

gdrive.overwrite_and_upload_to_drive(file_name, parent_id)

Upload to Google Drive with a rotating file handler

gdrive.upload_to_drive_with_rfh(file_name, parent_id, num_files)

Restore Backups

Download the backup file from google drive (say: backup.encr)

Decrypt the file

backup_handler.encrypt.encrypt_file('backup.encr', 'filename.tar.gz')

Decompressing the tar-gz dump

backup_handler.targz.unpack(source_path='filename.tar.gz', output_path='backup_dir/dump/')

Restoring the dump

backup_handler.backups.restore(bck_dir='backup_dir/dump/')

Hash Checks

To ensure that your backup file has not been tampered with, you can perform a SHA-256 hash check.

backup_handler.hash.generate_file_hash('source.file')

You can also save the hash into a txt file by executing

backup_handler.hash.save('hash.txt')

or print the hash by executing

print(backup_handler.hash.last_hash())

You can also compare the current generated hash with any other string using

backup_handler.hash.compare_generated('hash-string')
# returns True or False on comparision
