Misc
Reset Backup Information
If you want to make a full backup, you can reset the backup information. This will make all files to be backed up.
Encryption
If you configure the passphrase, the ZIP file will be encrypted by AES-256-CBC with the passphrase.
[!IMPORTANT] Not compatible with the encrypted zip file. We have to decrypt the file by OpenSSL, without this plug-in. Decryption command is
openssl enc -d -aes-256-cbc -in <encrypted file> -out <decrypted file> -k <passphrase> -pbkdf2 -md sha256.
What is backupinfo.md?
This markdown file contains a list of file information. The list is stored as YAML. backupinfo.md is also stored in each Zip file.
For the sake of simplicity, suppose we have three files, make a backup, change one of the files and make another backup.
Then we get the following.
