The Enterprise Vault
collector combines multiple archived items within a partition into
much larger collection files. The use of collection files may
significantly improve backup times for the partition, although
Enterprise Vault takes slightly longer to retrieve collected items.
The collection files are standard Windows CAB files.
Enterprise Vault single
instance storage can continue to share SIS parts after they have
Collection is not
recommended on any devices that perform deduplication, as it causes
loss of deduplication.
As users delete archived
items, the number of references to an item decreases. When no
references remain to an item, Enterprise Vault deletes the item.
Note however that if you use collections, unreferenced items may
remain in a CAB file for some time before they are deleted.
Enterprise Vault compacts a CAB file and deletes the unreferenced
items when the ratio of unreferenced items reaches a fixed

you configure a partition to use collection files, you cannot

Daily file collection times:
Start at. Enter the
local time at which you want collection to start.
End at. Enter the
local time at which you want collection 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
option to run collection on this partition immediately.
Limit collection files to <number>
megabytes. Enter the maximum size for collection files. The
default size is 10 MB. You may want to change this value to
optimize the use of your backup media.
Note the following:
The larger a collection file, the longer Enterprise
Vault takes to retrieve collected items.
For performance purposes, Enterprise Vault limits
the number of files that a collection file contains. Therefore
collection files may be smaller than the maximum size.
The Enterprise Vault collector does not add to a
collection file after the file has been created.
Collect files older than. Enter the amount of
time that must elapse since items were archived before they are
eligible for collection.
Note the following:
Enterprise Vault does not collect files until they
have been backed up. Do not set the elapsed time to less than your
backup frequency, otherwise Enterprise Vault wastes resources
repeatedly checking whether the files have been backed up.
To aid indexing performance, Enterprise Vault
should index items before they are collected. You should therefore
allow a minimum of one day before items are collected.
A long delay provides no benefit, except that until
collection occurs the items are retrieved more quickly.
