Page 121 SnapServer/GuardianOS 7.5 Administrator’s Guide 6 - Other Storage Options Snapshots and iSCSI Disks Running a GuardianOS snapshot on a volume containing an iSCSI disk will abruptly disconnect any clients attempting to write to the iSCSI disk and the resulting snapshot may contain inconsistent data.
Page 122 In the Duration field, specify how long the snapshot is to be active in hours, days, weeks, or months. The SnapServer automatically deletes the snapshot after this period expires, as long as no older unexpired snapshots exist that depend on it. If any such snapshot exists, its termination date is displayed at the bottom of the page.
Page 123: Schedule Snapshots
Step 3: Set the backup software to archive the latest version of the snapshot. The SnapServer makes it easy to configure your backup software to automatically archive the most recent snapshot. Simply configure your backup software to copy the contents of the directory within the snapshot share you created.
Page 124: Snapshot Space
Snapshot data grows dynamically for as long as a snapshot is active and as long as there is enough space available in the snapshot space to store them. When the snapshot space approaches its capacity (at about 95 percent), the SnapServer deletes the oldest snapshot’s data to create space for more recent snapshot data.

Page 128: Configuring Iscsi Initiators
Connectivity to the iSCSI disk is established using a software package or PCI card, known as an initiator, that must be installed on a client machine. The initiator sees the SnapServer as a “target portal” and an iSCSI disk as a “target.”...
Page 129: Iscsi Configuration On The Snapserver
For ease of management and particularly for data integrity and backup purposes, either dedicate the entire SnapServer to iSCSI disks, or if the server is to be used with other shared resources, place the iSCSI disk and the other shared resources on separate volumes.
Page 130 To ensure the fastest possible write performance, SnapServers can buffer up to 1GB of data to efficiently handle data being transmitted to a SnapServer. This widely accepted method of improving performance is not without some risk. For example, if the SnapServer were to suddenly lose power, data still in cache would be lost.
Page 131 Disk Naming Conventions iSCSI disks are assigned formal IQN names. These appear as the iSCSI device names that the user chooses (or types) when connecting from a client initiator to the SnapServer target, and also on the iSCSI disk details page.

Page 221 (DynamicRAID). If the volume or storage pool is deleted or rolled back from a snapshot, the SnapServer attempts to automatically relocate the BitTorrent Sync install directory to another volume or storage pool. If there are no more volumes or storage pools, or if none can be found that are large enough, BitTorrent Sync is disabled and cannot be re-enabled until a suitable volume or storage pool becomes available.

Additional Information on DynamicRAID Sizing About DynamicRAID • To increase the capacity of the storage pool when the SnapServer is fully populated, you can replace drives, one at a time, with larger-capacity drives. Replacing drives can only be done when the DynamicRAID is healthy.
Page 238: Should I Use Dynamicraid Or Traditional Raid
All of its features apply equally to both file sharing and iSCSI volumes created on the SnapServer NAS system. DynamicRAID uses clear visible indicators on the drive bays to illustrate what can or cannot be done to that bay, thus reducing user error and negating the need for any required skill set or training for operation.
Page 239 I need to be able to optimize parity based on the number of drives inserted into the system. I need the SnapServer to configure and manage the RAID array size and parity. I need to manually configure the RAID array.
Page 240: Setting Up Dynamicraid
During the setup process, storage pools are created on the head unit and each expansion unit using all disk drives available in that unit. More capacity can be added to a SnapServer over time by inserting or replacing drives, then adjusting Storage Pool properties. Volumes can be added and removed at will, and all volumes share the same underlying pool of storage.
Page 241: Snapshots
Indicators Drives can be inserted into the SnapServer NAS system at any time unless the user is specifically instructed not to do so. Each drive bay has an associated indicator which can be either red, amber, or green.
Page 242 SnapServer/GuardianOS 7.5 Administrator’s Guide A - DynamicRAID Overview Drives of different overall capacity may be added to the same storage pool as long as they have the same partition sizing (such as, 300 GB). However, the extra space on larger drives will only be available to the storage pool if there are enough larger drives to satisfy the storage pool's parity setting using the extra space.

Appendix C This appendix provides additional information and configuration options about securing and accessing shares and files on the SnapServer. The SnapServer GuardianOS supports share-, file-, and directory-level permissions for all local and Windows domain users and groups. File and directory security can be configured using either Windows NTFS-style security or classic Unix-style security.

Page 250: Share Level Permissions
SnapServer/GuardianOS 7.5 Administrator’s Guide C - Security and Access Share Level Permissions Share-level permissions on GuardianOS are applied cumulatively. For example, if the user “jdoe” has Read-Only share access and belongs to the group “sales”, which has Read/Write share access, the result is that the user “jdoe” will have Read/Write share access.

On the SnapServer DX1, the Reset button is accessed via a small hole next to the Power button on the front of the server at the top. On the DX2, the hole is located at the bottom of the Power panel on the right flange.
Page 258 SMB: Domain Controller unavailable SMB: Username not connected to Domain Controller This means that either your Domain Controller is down, or the SnapServer is unable to reach it. Because it cannot communicate with the Domain Controller, it is not able to authenticate the user.
Page 259 Ensure that the Ethernet cable is connected securely to both the network port and the server’s primary Ethernet port. Also, check to see that the Link light on the front of the SnapServer is lit (solid green). If the Link light is off, this is normally caused by a mismatch between the switch/hub and the Ethernet port on the SnapServer.
