Storage providers
gitdr writes to any S3-compatible or major-cloud object storage. Immutability (WORM / Object Lock) is a switch you flip on your own bucket. This table says which providers can give you that switch, so you can pick one that clears a ransomware-resistant bar. Most have a free tier.

¹ WORM / Object Lock is a feature you enable on your own bucket. gitdr writes to any supported destination regardless. This column says which providers offer a lock gitdr can read.
✅ supported · ⚠️ verify · 🔜 announced/roadmap · ❌ not available
A provider without the lock still works as a destination, gitdr warns loudly and
proceeds, or fails closed under --require-worm. Setup commands for the big three and
the S3-compatible quirks are in WORM buckets.
All product names, logos, and brands are property of their respective owners, used here only for identification and interoperability. gitdr is independent and not affiliated with, endorsed by, or sponsored by any listed provider.
