Policies

In order to enable snapshot management for Storage Instance you need to do the following steps:
Go to Snapshot SLAs under the Storage section and create a new Snapshot Management policy:
As well as other types of Policies, you'll also find 4 main sections here:

General

Under this section you can set up:
  • Name of policy
  • Enable/disable this policy
  • Snapshot Retry Count - how many times, Storware will try to repeat the snapshot task
  • Set priority for the task

Auto-assignment

In this section you can set up:
  • Mode
    • Disabled
    • Assign only
    • Assign and remove
  • Include or exclude rules based on regular expression matching Storage Instance name, i.e.:
    • regular expression examples:
      • .* match any character any number of times
      • storage-[0-9][0-9][0-9] - match name that starts with storage- and 3 digits
      • (prod|uat|dev)-[0-9][0-9][0-9][a-z]? - match the name that starts with prod or uat or dev prefix, then -, then 3 digits and optional lower-case letter (matching is case-sensitive)
    • exclude rules always take precedence over include rules
    • Storage Instances may not be reassigned to the different policy if they already have a matching policy assigned
    • Storage Instances may be reassigned to the different policy only if mode is assigned and remove, current policy assignment rules don't match, and other's policy rules match
    • rules are joined with OR operator, so
      • if any rule (tag or matched regular expression) excludes Storage Instance - it will be excluded
      • if no rule (tag or matched regular expression) excludes Storage Instance, and any rule (tag or matched regular expression) includes Storage Instance - it will be included
    • You can also select Storage Pools to match only Storage Instances that belong to them
In this place, you can select storage instances manually in a simple way.
Provide retention settings - how many snapshots (created by this policy) will be kept and for how long. If you have already created a schedule, you can also select it.
