Data Migration Default Quota Assignments For users and groups, there are no pre-assigned default quotas on the Snap Server. When quotas are enabled on the Snap Server, you can assign a default quota for all users, or allow all users to have unlimited space on the volume. Unless you assign individual user or group quotas, all users and groups will receive the default quota. How the Snap Server Calculates Usage In calculating usage, the Snap Server looks at all the files on the server that are owned by a particular user and adds up the file sizes. Every file is owned by the user who created the file and by the primary group to which the user belongs. When a file is copied to the server, its size is applied against both the applicable user and group quota (NIS groups only). Setting User Quotas You can set individual quotas on a per-volume basis for any local user, Windows domain user, or NIS user or group known to the Snap Server. Note Specific individual user quotas always override the default quota. Data Migration Use the Data Migration feature to migrate data from a legacy Snap Server or other computer that supports CIFS or NFS to a new Snap Server. The Data Migration (DM) feature can be used to copy or move files and folders from a server on the network (source) to a Snap Server (target). To access the Data Migration utility, navigate to Maintenance > Data Migration. If an error is encountered during migration (e.g., a file or folder is locked and cannot be migrated), the DM utility records the error in a log, and continues the operation. When the migration is completed, the administrator can view the log of migration errors. Once the errors have been corrected, the user returns to the DM main screen, and recreates the migration. With the exception of the password, all fields will still be populated with the specifications of the last job. The following migration options can be specified: • Copy or move data • Include subfolders • Overwrite existing files 50 Snap Server Administrator Guide

Snap Server Administrator Guide
Default Quota Assignments
For users and groups, there are no pre-assigned default quotas on the Snap Server.
When quotas are enabled on the Snap Server, you can assign a default quota for all
users, or allow all users to have unlimited space on the volume.
Unless you assign individual user or group quotas, all users and groups will receive
the default quota.
How the Snap Server Calculates Usage
In calculating usage, the Snap Server looks at all the files on the server that are
owned by a particular user and adds up the file sizes. Every file is owned by the
user who created the file and by the primary group to which the user belongs.
When a file is copied to the server, its size is applied against both the applicable user
and group quota (NIS groups only).
Setting User Quotas
You can set individual quotas on a per-volume basis for any local user, Windows
domain user, or NIS user or group known to the Snap Server.
Note
Specific individual user quotas always override the default quota.
Data Migration
Use the Data Migration feature to migrate data from a legacy Snap Server or other
computer that supports CIFS or NFS to a new Snap Server. The Data Migration
(DM) feature can be used to copy or move files and folders from a server on the
network (source) to a Snap Server (target).
To access the Data Migration utility, navigate to
Maintenance > Data Migration
.
If an error is encountered during migration (e.g., a file or folder is locked and cannot
be migrated), the DM utility records the error in a log, and continues the operation.
When the migration is completed, the administrator can view the log of migration
errors. Once the errors have been corrected, the user
returns to the DM main
screen, and recreates the migration. With the exception of the password, all fields
will still be populated with the specifications of the last job.
The following migration options can be specified:
•
Copy or move data
•
Include subfolders
•
Overwrite existing files
