- Backups can be stored in cloud storage like S3, Azure, Google Cloud Storage etc.
- Point-in-time recovery allows restoring database to a specific timestamp.
- Works across different platforms like Linux, macOS and Windows.
- Compressed backups to save disk space.
- Backup monitoring and logging capabilities.
- Open source tool with community support.
Overall, WALE is optimized for backing up large PostgreSQL deployments efficiently with minimal overhead on production systems. Its incremental nature and use of replication protocol makes taking frequent backups feasible.
