Customizing Schedules

• Weekly Backup Schedules
• Creating Schedules

The two main factors in determining the type of backup schedule are:

• Estimating the amount of time that can be dedicated to performing a full backup.
• Capacity of the backup device, where for full backup the device capacity must be ³ total data disk capacity.

The optimal time for performing the backup is when the server is acquiescent (with few files open). This is either late at night or over a weekend.

• Calculate the necessary backup time for a full backup and then see how this fits into the existing workflow.
• The rule of thumb for calculating the maximum time for a full backup is:

* Where 15GB/hour is the accepted backup rate for DLT7000 Series Magnetic Tape devices. The rate may vary depending on the platform and SCSI type.

For a 180GB RAID and Q2-15 Jukebox the calculation is as follows:

It is recommended that a weekly Full Backup be performed over the weekend.

If the plant works every day in three shifts, a sliding schedule of Full Backups should be planned.

• NetWorker provides five pre-configured schedules and the ability to create customized schedules.
• The default schedule is Full Backup every Sunday and Incremental Backup every day. This is the recommended schedule, if there is no work over the weekend.

Identical Start Time for Full and Incremental Backup

If you are using the default schedule, Full Backup every Sunday and Incremental Backup every day, skip this section.

1. To create a weekly backup schedule, choose Customize from the menu bar, then select Schedules from the pull-down menu.
2. Click the Create button.
3. Enter the name of the schedule into the Name text field (e.g., Full on Saturday).
4. Select Week as the Period.

5. To select a day for the full backup, select the specific day of the week from the current month calendar displayed and pulls down the Backup Level menu.
6. Select full from this menu.

7. To ensure that all other days are marked for an Incremental Backup, select the day of the week to begin the Incremental Backup and pull down the Backup Level menu.
8. Select incr and click Apply to save this new schedule.

• If you want no backup at a certain day, choose skip on that day.

Enable the Default group to which the client belongs. When the default group is enabled, the NetWorker backs up all clients in the group according to the pre-configured selections.

• For further explanations of Client and Group, refer to the manuals supplied with the Legato NetWorker.

1. Choose Customize from the main menu bar and then choose Groups.
2. From the Groups text field, select the group required, in this case, select the Default group.
3. Set the Start time for the backup according to your requirements, in this case, both Full and Incremental Backups begin together at the configured time.

4. Set Autostart to enabled.
5. Select Apply, then choose Exit from the File menu to close this window.

• Each backup schedule must have a client for the schedule.
• When NetWorker is installed, it becomes a client of itself.

1. Choose Clients from the menu bar and then choose Client Setup.

The Clients dialog window is now displayed.

2. The Clients text field displays the server name.

If you are using the default schedule then proceed from step 6 and update the different policies.

If you need to create a client, proceed from step 3 (for a Sliding Schedule, refer to Creating a Sliding Backup Schedule in Customize Setup).

3. Press the Create button.
4. In the Name field type in the name of the client that is to be created, in this case, ripro1.stil.scitex.com (the suffix stil.scitex.com indicates that a domain server is installed). The client name is usually ripro1.

Note: The suffix will be different depending on a customer’s DNS setup.

5. Now proceed to fill in the parameters for this client.
6. At the Schedule text field, select the triangular indicator to display a list of schedules, then select the schedule you require.

At the Browse policy text field, a list of policies can be similarly displayed.

The Browse policy selected reflects how long the file entries remain in the file indexes before being automatically removed. The recommended setting is 2 weeks for backup.

A Full Backup remains in the on-line index for a period of time equal to the Browse Policy plus one complete backup cycle. This setting determines the number of cartridges required.

At the Retention policy text field, a list of policies can be similarly displayed.

The Retention policy selected reflects how long the save sets on a volume will be recoverable before the volume is available for recycling. The recommended setting is 2 weeks. It must be equal to the Browse policy setting.

At the Directive text field, a list of policies can be similarly displayed.

The Directive policy selected is an instruction set created to maximize the efficiency of a backup and handling of special files. The recommended policy is Unix standard directives.

Note: Do not use the Unix with Compression Directives option due to hardware compression, which is default.

7. Verify that Group is set to default.
8. Set the Save set text field to the appropriate client filesystem(s) for the selected NetWorker client and change the default setting All to /dataVolumes/*, then press the Change button.
9. Select Apply when all settings are complete.
10. Choose File and then choose Exit to return to the NetWorker Administration window.

This ends the basic Legato Backup configuration.

Different start time for Full and Incremental Backups

1. To create schedules for each type of backup, refer to Weekly Backup Schedule above.

2. To select a day for the Full Backup (in the first example, Saturday) from the current month calendar displayed, select the specific day of the week and pull down the Backup Level menu.
3. Select full from this menu, to mark (f) all Saturdays appropriately.
4. Since there is no Incremental Backup (e.g., day after the Full Backup), pull down the Backup Level menu and select skip from this menu for all days but Saturday.
5. Click Apply to save this schedule.

6. For the second schedule, follow the above procedure but select incr to determine the days for the Incremental Backup only and select skip for the days for the Full Backup.
