Which type of copy must be performed for the initial backup of an Open Systems platform directory to the SnapVault secondary storage?

• A. Temporary copy
• B. Incremental copy
• C. Initial baseline copy
• D. Scheduled update copy

Answer: (C)

The initial backup to SnapVault must be a baseline copy because SnapVault needs a complete, reference copy on the secondary to seed the backup set. This full baseline mirrors the Open Systems directory exactly, establishing all data and metadata on the secondary. Once this baseline exists, subsequent backups can be incremental, sending only the blocks that changed since the baseline (or since the last incremental). An incremental copy cannot stand alone as the first backup because there is no prior copy to compare against. A temporary copy isn’t used to seed the first mirror, and a scheduled update copy describes periodic updates rather than creating the initial seed.
