we are looking into our backup strategy and investigating few scenarios of backend storage. Right now we are considering object storage via S3 protocol and file storage (JBOD) over NFS protocol. The data which will be send there is on-prem filesystems, databases, VM’s etc. Total capacity - over 10 PB.
Currently we tested some object storage over S3 protocol but we faced issues with data reclamation (garbage collection for expired objects taking way too long and capacity reclaimed wait time takes over month or few).
Can you share your experience with back-end storage, what challenges you faced or how you solved my mentioned issues, also, what advantages you see comparing S3 & NFS protocols for backups.
All feedback is very appreciated.
