Set SnapVX snapshot time to live (TTL)

Description

Use the set ttl option to set the time to live for a regular snapshot either as a number of days from set time or an absolute date in the future. Only snapshots without links or restore sessions can be terminated. If the snapshot has links it will be terminated when the last link is unlinked.

NOTE:Once the TTL is set for snapshot it can only be extended forward in time and not set back in time. Refer to Examples below for invalid TTL values.

  • -delta Days[:hours] — Sets TTL to 1 – 400 days plus 0 –23 hours from current host time. Day Format is days:hours (for hours, only whole numbers are valid and 0 value is optional).
  • -absolute Date[:hour] — Sets TTL to an absolute date in the future, up to a date 400 days from current host date, plus 0 –23 hours. Date format is MM/DD/YYYY:hours (for hours, only whole numbers are valid and 0 value is optional).
  • -delta NONE - Removes TTL.
