Solution

Check if EV services are running.

1. If all EV Services have stopped, the issue may be caused by low disk space.. EV Admin Service writes a warning message to Windows Application Log if 95% of disk space is used. If 99% of disk space is used, all EV Services will stop.Details can be found in the following article from Veritas: https://www.veritas.com/support/en_US/doc/122185187-122185191-0/v11738504-122185191
2. It may happen that only EV Storage Service is not running and all other services are running. It can be caused by low disk space or unavailability, even if only one partition is affected.

1. 1. Check disk space on a Vault Store partition.
      If there are several partitions, check disk space on all of them.
   2. Check if partition location (physical folder) is available. EV Storage Service checks the Vault Store partitions, after start. If even one partition location (physical folder) is not available, e.g. is missing or can not be reached for whatever reason, EV stops the Storage and Task Controller services.

Reasons for full disk space

A closed partition may increase in size and needs to be backed up due to the following reasons:

1. Deletion
   Enterprise Vault modifies the partition if users delete items from their archives.
2. Storage Expiry
   Enterprise Vault deletes items from archives when their Retention Periods expire.
3. Collections
   The Enterprise Vault Collector continues to run on a closed partition. Collections are required on closed partitions because the collection process removes temporary files that are created when users view archived items.
4. Pending Items
   Items that are in a pending state before the partition is closed, result in writes to the closed partition.

If a closed partition is likely to be modified, it is recommended to perform regular backups of the closed partition.
If a closed partition is never modified, regular backups are not required. It is sufficient to perform a final backup of the partition and then remove the partition from a backup routine.
