You have arrived at this screen through Savepack
[name] > Manage trees
. In this screen, the filenames
of data to be backed up are added or deleted, and Tree options can be
changed.
A Tree is a directory, or folder, on a client computer's HDD, and all the sub-directories and individual files it contains. More than one Tree can be added to a Savepack.
There are two ways to create a Tree of files to be backed up:
Click on Home > Backups >
Savepacks
and select the Savepack from the Select a
Savepack
list into which this Tree will go.
Click on Browse trees for
[Savepack name]
Click on root
in the navigator window to start
searching for the data to be backed up in this Tree. Each box you
check will add the corresponding directory as a Tree in the
Savepack.
When all the Trees for this Savepack have been selected, click on
Update
to save them.
Select the Tree to modify from the Select a tree
list,
or click on Add a new tree
in the
actions menu.
Trees can have the same options as Savepacks. The defaults for these common options are as for the parent Savepack. A change made to an option in a Tree will override the same option in the Savepack, but only for that tree.
Add a new
tree
, enter a FQDN pathname for the data to be backed up in
this Tree. If you selected this tree, the pathname will already be shown.Object backup command
field. Please note that the file created by the Object command will
not reside on the Arkeia client, but an entry will be created in the
Arkeia database to restore the data backed-up.
Arkeia will not perform the backup if the command entered in the
Command before Tree field fails and returns a standard error code. For
instance, if a tar
command should be performed on some
files before the backup, and tar
returns a standard error
code (an error code larger than 0 -- Success
, then Arkeia
will not perform the backup.
If the command did not perform as expected and returned an error code,
but the backup should be performed nonetheless, click on the check box
Backup Savepack
if command fails below the entry field.
A command can be any standard UNIX command, a shell program, a batch
file (on Microsoft® Windows® computers) or any other program
that can be launched from a command line. The following commands are
valid entries for a Command before Tree
:
machine_fqdn!file:/home/john/scripts/dump.pl (Perl script on a Linux machine)
windows_fqdn!file:c:/Program Files/Arkeia/Arkeia/myscript.bat (batch script on a Windows machine)
Execute if Tree
backup fails
check box below the entry field.The Multiflow value determines if Arkeia should launch a backup tree with several concurrent data flows.
By default, the value of Multiflow is 0 for all trees, meaning that Arkeia will use only one data flow between the server and the client, and will backup the trees in a sequential order.
To create more than one data flow (and, therefore, launch parallel backups), a value other than 0 should be entered in this field. For instance, if three trees are contained in a Savepack, the following values could be applied:
A (sargon:/home/pete/) | |
B (sargon:/home/tina/) | |
C (sargon:/home/www/) |
In the example above, three trees are created in a Savepack, and
each of these trees has been assigned a different flow number. When
the Arkeia backup server is going to backup the Savepack, it will
open three different flows to the computer sargon
, one for each of
the trees, and backup all the trees at the same time.
If two of these trees are assigned the same Multiflow number, they will be backed-up sequentially, instead of at the same time.
A (austin:/home/sal/) | |
B (abilene:/home/tc/) |
Yes
if you want the file ACLs (Access Control
Lists) in this tree to be saved on backup. The value No
means that Arkeia will ignore any ACLs when backing up this
Tree. Note that the setting of Backup POSIX ACLs in Tree
advanced options
can override the setting you enter
here. Setting POSIX ACL backup to Yes
increases the
processing overhead for every file, whether or not the file uses
ACLs. For this reason, the default is No
for ACL backup.
Click on Add tree to add this Tree to the Savepack. More Trees can added, if necessary.
