A finance group handles large transaction data and keeps backups at another location. They want confidence that smaller records can be restored if part of their recent data goes missing. Which method addresses these needs and includes a step to confirm stored information?
Mirroring sessions to a standby environment
Periodic differential capturing
Incremental synchronization and verification
Full images stored locally using a non-incremental approach
Incremental synchronization and verification captures updates on a recurring basis and checks the archived data for integrity, helping retrieve subsets. Full images stored locally use significant resources and do not confirm smaller portions regularly. Periodic differential capturing may miss errors that occur between intervals. Mirroring sessions do not incorporate a step that tests smaller data retrieval.
