In order to use Migration, Collections must first be enabled.
1. Go to the desired partition to enable Collections and Migrations under Vault Stores in the Vault Administration Console (VAC).
2. Right-click the vault store name and select Properties.
3. Collections can be enabled by checking the box next to Use collection files on the Collections tab.
4. To enable migration of collected files go to the Migration tab and check the box next to Migrate collection files.
The information below details the behavior of the various settings in each of the tabs.
Vault Store Partition Properties: Collections
Enterprise Vault Collector combines multiple small files on the partition into much larger, collection files, which may give you a significant improvement in backup times. The collection files are standard Windows CAB files.
You can configure the maximum size of the collection files to suit your backup device, but there are several other rules that Enterprise Vault Collector uses that you may want to be aware of:
-- All files of the appropriate age are collected.
-- A collection file never contains more than 25,000 files.
-- Files are collected provided that they are no bigger than the maximum collection file size.
-- Enterprise Vault Collector does not add to a collection file when the file has been created. Thus, you may find that you have collection files that are less than the maximum size.
Use Collection files. (Not shown for Centera partitions.) If you want to use file management software, check this and then choose the collector software you want to use from the list and customize the collection behavior as required.
Note that, when you have enabled file management software for a partition, you cannot go back to None.
Daily file collection times:
-- Start at. Enter the local time at which you want collecting to start.
-- End at. Enter the local time at which you want collecting to finish. Enterprise Vault stops collecting at this time or when it has no more files to collect, whichever comes first.
-- Run Now. Click this to run Enterprise Vault Collector on this partition immediately.
Limit collection files to <number> megabytes. Enter the maximum size for collection files. The default size is 200 MB (in version 8.0 the default size is 10); you may want to change this to optimize the use of your backup media.
Note that increasing the size of collection files means it takes longer to restore archived items because Enterprise Vault must recall complete collection files before extracting the files to be restored.
Collect files older than. Enter the amount of time that must elapse since files were last modified before they are eligible for collection.
If you have chosen to share duplicate archived items you must leave a longer time than if you have chosen not to share items. This is because items that are eligible for sharing may not all be archived at the same time. By leaving the files on disk for several days you allow time for sharing to occur.
Vault Store Partition Properties: Migration
Migrate collection files. Enterprise Vault can automatically migrate collection files from an NTFS or network share vault store partition to a secondary storage location. The migration can help reduce storage costs by moving collection files to cheaper secondary storage devices. The drawback is that retrieval times increase.
Note that this functionality requires a separate license.
-- Migrate files older than. Specify the age at which each collection file is to be moved to secondary storage.
-- Remove collection files from primary storage. Files that have been copied to a secondary location can remain in their primary location for the period of time you specify here. This means that you can, if necessary, allow time for the secondary storage to be backed up before deleting the files from the primary location.
-- Secondary storage location. Shows the location to which this partition's collection files are migrated. When you have selected a secondary location and applied the new setting, you cannot change to use a different location.
