How SnapVault maintains compliance

SnapVault uses a SnapLock volume and an append-only write to write to the log files.

SnapVault uses a SnapLock volume in which the log files are kept. This volume, called SnapLock for SnapVault log volume, is a standard WORM volume. SnapVault uses an append-only write to write to the log files. This allows accurate record keeping but does not allow previous events to be overwritten.

SnapVault uses two types of log files to record events:

• SnapVault operations log files
• SnapVault files-transferred log files

• Operations log file
  SnapVault creates a new log file every Sunday morning at midnight, based on the ComplianceClock. Any SnapVault operations that are active when the new log file is created are recorded in the new log file. Operations log files have a weekly rotation policy.
• Files-transferred log files
  SnapVault creates a new files-transferred log file at the beginning of each SnapVault transfer.
