# Changelog
|
||||
|
||||
## 1.0.0
|
||||
|
||||
### General
|
||||
- Versioning of Nextcloud-Backup-Restore.
|
||||
- The database system (MySQL/MariaDB or PostgreSQL) is configured in the variable area of the scripts, so it's not necessary to comment/uncomment the specific database commands.
|
||||
- Special characters for the database password can be used now.
|
||||
- Single quotes for variables.
|
||||
|
||||
### Restore
|
||||
- The commands for retoring the database are checked at the beginning of the script. Is the specific database system is not installed, the restore is cancelled.
|
||||
- The default main backup directory now is the same as in the backup script.
