Immediate backup to disk
Configure and run an immediate backup to disk job in this screen by choosing
from the drop down lists. If the Savepack or VTL Drivepack you want to use for
this backup job does not already exist, create them or change existing
packs.
- Savepack
- Click on this drop-down list to present the Savepacks
that have been defined and can be selected to be backed-up.
- VTL Drivepack
- Click on this drop-down list to present the different VTL Drivepacks that
have been defined and can be used to perform the backup to disk
operation.
- Type
- Choose in this field the type of backup that will be started, as well
as the completion strategy for a backup. The three different types of
backups are:
- Total
- A total backup job will backup all files and directories defined
in the Savepack. Total backup data sets have a Valid for
period, after which the VTLs containing the total backup data set can
be recycled automatically.
- Incremental
- In an incremental backup job, only files that have been created
or modified since the last backup are written to the backup data
set. The last backup which may have been either a total
backup or an incremental backup, is by default the last backup done
with this Savepack. A specific backup on which to base this
incremental backup can be selected in the From field.
- Archive
- An Archive backup job will backup all the files and directories
selected in the Savepack, and will retain the data indefinitely. This
prevents Arkeia from recycling the VTL automatically.
Each type of backup can be further configured with the following
completion strategy:
- Standard
- The Standard completion strategy completes the backup once all
the data contained in the defined Savepack has been sent to the Arkeia
backup server. The backup itself is considered as finished, logged as
such in the Arkeia logs, and all hardware peripherals used by the
backup are released by the server so become available for other
tasks. This is the default completion, and we recommend that it be
used most of the time.
- Continuous
- If a Continuous completion strategy is chosen, once the backup
has finished saving the data contained in its Savepack, it stays
active and is not considered as completed by Arkeia Network
Backup. The hardware used for the backup operation is still considered
as reserved by the Arkeia backup server, and cannot be used for other
operations. It is possible to add new Savepacks to the backup, as long
as the backup has not been terminated by the user.
Caution
The continuous completion strategy should be used with
caution. Generally it is only needed by some Arkeia plug-ins which run
hot backup jobs. In any case, Continuous completion should
never be used for Scheduled (unattended)
backups!
- From
- It is possible to backup all the files which have changed since
some earlier backup instead the very last backup of this data. In
this field, choose the previous backup on which you want to base the
incremental backup.
- Valid for
- This field determines the duration of data retention. Once the data
retention period has expired, it is removed from the VTL(s). Note that this
parameter is modified if the backup type is set to Archive. In this case, the
retention date is canceled and the data is never recycled. The retention date
can be manually overridden to force Arkeia to recycle the data.
- Parallelism
- This field determines the number of parallel flows that should be
open between the Arkeia backup server and the Arkeia client when
performing the backup.
- Emails
- Arkeia log messages can be emailed to the logged in user, and one
other eddress, provided the address was supplied when the user's
account was created.
- Advanced parameters
- To set a parameter when the backup job runs, enter the
parameter and its value then click on
Add
.
- Tag
- This field determines a name that can be used to identify the
backup. Once this name has been entered, it can be used to identify
the backup and all the data it contains when performing a restoration.
- Comment
- Use this field to enter a longer, more detailed
description of the backup.
Click on Start backup
to launch the backup job you
have configured, and the Show backup
screen will display
information on the progress of the backup job, and allow you to abort
it or change between continuous and standard completion modes.
