4. Pad missing data blocks with nulls?: When a data sync error occurs, assuming the reading is setup
to continue, the missing data will be padded with NULL bytes by default (the field is set to yes). This is
to ensure that, although the data has been altered, it remains in the correct alignment.
It is very important for the data to remain in the correct alignment when restoring
raw device backups (logical/ZFS volumes, slices or meta-disks). If you do not pad
sync errors with NULL bytes, all of the data following the error would be restored to
a different location than expected.
Volume Group , Zpool , Filesystem and
File/Directory backups use an underlying restore command that is capable of re-
synchronizing when there is missing data in the data stream. Therefore, the value of
this field is less relevant when restoring from these backup types. However, the
restore command may sometimes fail when it encounters too large of a stream of
NULL bytes. In this case, it may be advisable to change this value to "no".
When all changes have been made, press the
Save button to save changes and exit this function. If you are
unsure of your changes and want to return to the system defaults, press the Defaults button. After doing so, all
data in the fields will be replaced with the defaults and you must then press Save to save them.
Change Access Permission of a Disk Backup
This option is not available when using Workstation Edition .
When a backup is performed, one of the options of the
backup profile allows you to specify the read permission
of backups written to disk. This is because a disk file is, by default, readable by any user, local or remote. Since
the disk backup files may contain confidential information, this is often not advisable.
The Backup Administrator automatically makes the contents of the file readable only by the root user of the
local or remote system, whether the file itself is readable or not. In the
backup profile , you may also specify
whether only the original client that wrote the backup may read the contents, or any client with access to the
directory on the backup server. If you plan to allow the backup of one client to be restored or installed onto
another client system, you must permit other clients access to the backup. If you did not do so when the backup
was created, this option will allow you to change your mind.
To change the client access to a backup, select Utilities !Change Access Permission of a Disk Backup . A
screen similar to the following will appear:
You will be asked to select the Server name and the Backup Device to which the desired backup was written.
The directory or directories specified by the device will be searched and a list of backups will be displayed.
Some of the backups may be part of the same Backup ID if there were multiple clients included in the same
