Protecting important data means storing multiple copies in different locations. While S3 Explorer doesn’t automate Cross-Region Replication, it gives you the tools to manually copy objects and preserve previous versions. Enable Versioning in the bucket’s inspector panel to retain old versions of every file. This alone is a simple form of disaster recovery because you can restore deleted or overwritten content at any time.
For further protection, you can periodically copy critical folders to a second bucket in another region. Use the Copy function described in the Data Transfer guide. By scheduling these copies or using external automation, you can approximate multi-region redundancy without complex setup.
If you operate an archive bucket, consider configuring lifecycle rules to transition older versions to Glacier storage. This keeps costs low while maintaining a history of your data. Should an entire bucket be lost due to accidental deletion or region outage, simply recreate it and copy your archived objects back.
Another practical technique is to periodically export object lists to a CSV file using the bulk operations menu. Keeping an offline inventory helps verify nothing was missed when restoring from backups and gives auditors a reference of what existed at a point in time.
The recommended click path for setting up versioning is: Sidebar → select bucket → Inspector panel → Versioning tab → Enable. For manual replication: Sidebar → choose source objects → right-click → Copy → pick destination bucket.
