Terminate the pod completely, instead use a network storage in a popular region.
Network storage are essentially like "external harddrives" you can imagine, which any pod can persist data too. Usually under /workspace.
For ex. if you launch a network storage under region A, you can launch two pods on that network storage, and they are sharing that drive.
The problem with network storage is that they can be for really large files be slow if ur reading directly from it (but you can just move it outside of /workspace onto the actual machine and will be faster + also it locks u into a region
