Remote store restore optimization

[prayascoriolis]

Description

Key changes made:

• Added a check to detect if there is preexisting data in the remote store.
• Modified the copySegmentFiles call to skip remote upload when data already exists by passing null instead of remoteDirectory.
• Preserved all other functionality including local file copying and verification.

This solution:

• Prevents unnecessary uploads when restoring from an interop enabled repository.
• Maintains data consistency by still performing local copies.
• Preserves existing recovery state tracking and error handling.
• Optimizes performance by avoiding redundant network transfers.
• The change is backward compatible and maintains the existing recovery mechanisms while eliminating the unnecessary upload step when data already exists in the remote store.
