Reasons to delete Snapshot copies

Delete older Snapshot copies to free space on the storage system volume, or to keep fewer Snapshot copies.

You might delete older Snapshot copies for the following reasons:

  • To keep fewer stored Snapshot copies than the hard limit of 255 on a storage system volume. Once it reaches the limit, attempts to create new Snapshot copies fail.

  • To free space on the storage system volume. Even before the Snapshot copy reaches the limit, a Snapshot copy fails if the disk does not have enough reserved space for it.

  • You can also use the wildcard (*) character in Snapshot copy names. The Snapshot show operation enables you to use the wildcard character to show all Snapshot copy names that match a certain pattern. The following rules apply to using wildcard in Snapshot copy names:

    • You can use a wildcard at the end of the name only. You cannot use the wildcard at the beginning or the middle of a Snapshot copy name.

    • You cannot use the wildcard in the storage system or storage system volume fields of a Snapshot copy name.
