Version
|
The version of NDMP that your DMA supports.
|
TCP port (v4 only)
|
The NDMP default connection port is 10000. NDMPv3 always uses this
port. NDMPv4 allows a different port if needed.
|
Ignore metadata-only changes
|
Directs the system to backup only files in which content has
changed, ignoring files for which only metadata, such as permissions
or ownership, has changed. This option only applies to incremental
"tar" and "dump" backups and is disabled by default.
|
Target restore pool(s)
|
When you perform a full restore using "tar" or "dump", the system
re-creates datasets if there is no share mounted at the target.
Because the NDMP protocol specifies only the mount point, the system
chooses a pool in which to recreate projects and shares. On a system
with multiple pools, this property lets you specify one or more
pools. Multiple pools only need to be specified in a cluster with
active pools on each head. You must ensure that this list is kept in
sync with any storage configuration changes. If none of the pools
exist or are online, the system will select a default pool at
random.
|
Allow token-based backup
|
Enables or disables token-based method for ZFS backup. This
property is off by default.
|
ZFS rollback before restore (v4 only)
|
Only applies to backups with type "zfs". Determines whether when
restoring an incremental backup the system rolls back the target
project and share to the snapshot used as the base for the
incremental restore. If the project and shares are rolled back, then
any changes made since that snapshot will be lost. This setting is
normally controlled by the DMA via the "ZFS_FORCE" environment
variable, but this property can be used to override the DMA setting
to always rollback these data sets or never roll them back. For
details, see NDMP Incremental Backups. Not rolling them back will cause the restore to
fail unless they have already been manually rolled back. This
property is intended for use with DMAs that do not allow
administrators to configure custom environment variables like
ZFS_FORCE.
|
Allow direct access recovery
|
Enables the system to locate files by position rather than by
sequential search during restore operations. Enabling this option
reduces the time it takes to recover a small number of files from
many tapes. You must specify this option at backup time in order to
be able to recover individual files later.
|
Restore absolute paths (v3 only)
|
Specifies that when a file is restored, the complete absolute path
to that file is also restored (instead of just the file itself).
This option is disabled by default.
|
Share creation on restore
|
Configures the restore operation to create a new share based on
the backup type:
-
All - Allows all backup
types to create a new share on restore
-
Tar_Dump - Allows
backup types "tar" and "dump" to create a new share on
restore
-
ZFS - Allows backup
type "zfs" to create a new share on restore
-
None - No backup type
can create a new share on restore
|
DMA tape mode (for locally attached drives)
|
Specifies whether the DMA expects System V or BSD semantics. The
default is System V, which is recommended for most DMAs. This option
is only applicable for locally attached tape drives exported via
NDMP. Consult your DMA documentation for which mode your DMA
expects. Changing this option only changes which devices are
exported when the DMA scans for devices, so you will need to
reconfigure the tape devices in your DMA after changing this
setting.
|
DMA username and password
|
Used to authenticate the DMA. The system uses MD5 for user
authentication
