Back up a bucket
Alibaba Cloud offers several ways to back up data in Object Storage Service (OSS). This topic describes the main methods to back up your OSS data for different scenarios.
Backing up a bucket incurs fees for requests and data retrieval. For details about fees, see the pricing for the backup method that you use.
Back up data using scheduled backups
Cloud Backup lets you create a backup schedule to back up your data from OSS to Cloud Backup. If your data is lost due to accidental modification or deletion, you can recover it promptly. You can also use Cloud Backup to store historical OSS data long-term at a low cost. For configuration instructions, see Scheduled backups.
Back up data using cross-region replication
Cross-region replication automatically and asynchronously copies files between buckets in different OSS data centers (regions). This near-real-time replication copies operations, such as file creation, updates, and deletions, from a source bucket to a destination bucket in another region. For configuration instructions, see Set up cross-region replication.
Create a backup using Data Online Migration
Data Online Migration is a data tunnel service provided by Alibaba Cloud for its storage products. You can use Data Online Migration to easily migrate data from third-party sources to OSS. You can also use it for flexible data migration between OSS buckets. For configuration instructions, see Migrate data between Alibaba Cloud OSS buckets.
Back up data using the ossimport tool
ossimport is a tool for migrating data to OSS. You can deploy ossimport on a local server or an ECS instance to migrate data from local servers or other cloud storage services to OSS. For configuration instructions, see ossimport overview.
