We wanted to create a comprehensive backup configuration with these characteris- tics:

• A total backup each month, which allows us to restore data as it was at the end of any month during the last 3 months.

• A total backup at the end of each week which allows us to restore data as it was at the end of any week during the last 3 weeks.

• Incremental backups which allow us to restore data as it was at the end of any day since the last total backup.

We clicked on to start creating the total backup con- figuration, and noticed that some backup configurations had already been created by other departments in the orga- nization. Our Sports Centre data is on a shared server.

We clicked on to open the wizard, Periodic

backup then selected

monthly/weekly/daily from the three alternatives.

We clicked on to

continue creating the backup configuration.

Here we set the backup oper- ation start days and times.

Monthly total

Set to start just after mid- night on the first morning of every month. The Validity period is 3 months. No monthly total backup data set which is less than 3 months old will be deleted or overwritten by

Arkeia Smart Backup. A monthly total backup data set which is older than 3 months, can be overwritten with new backup data by Arkeia Smart Backup.

Weekly total

Just after midnight on every Sunday morning, a total backup will be started. A total backup in the weekly schedule will be kept for 3 weeks, after which it may be overwritten by Arkeia Smart Backup.

Daily incremental

Just after midnight every day, an incremental backup will be started. This will backup any files which have changed since the last backup, of any type, was done. Each data set created by this backup will be kept for 7 days, after which they may be overwritten by Arkeia Smart Backup.

Backup operation priority

You may be wondering what happens to the daily incremental backup operation when a weekly or monthly backup operation is scheduled. Before

Arkeia Smart Backup starts a daily backup, it

1. checks to see if a weekly backup operation is scheduled for the same time, then

2. checks to see if a monthly backup operation is scheduled to start at the same time

If weekly or monthly backup operation is scheduled for the same time, the daily backup operation is cancelled for that instance and the weekly or monthly is run. Similarly, if a monthly backup operation is scheduled to run at the same time as a weekly, the weekly is cancelled and the monthly is run.

We entered a name for this backup configuration and checked the Activate this

backup policy box, to ensure that it will run.

Command before and after backup

It is necessary to run the scripts which start and stop any processes which have opened the files in the data to be backed up, and we set this up in the screen shown here. We checked the Exe-

cute command if backup fails box to ensure that everything would be re- started for the next day.

The commands run by Command before and Command after must return a zero error code, otherwise Arkeia Smart Backup will assume the command failed (even if it did not). If the command returns nothing, Arkeia Smart Backup assumes it failed.

Disaster recovery

If you have an Arkeia Disaster Recovery (DR) plugin license, check the Disaster

recovery info allowed box, if this data is to be part of your DR backup data set. This will ensure that details needed for DR will be included in the backup data set.

Incremental > Differential

Check this box if you want the daily backup operation to be a differential backup, which will capture in each backup data set the files changed since the last total backup. We wanted the data set from this backup to contain files changed since the last incremental backup, or last total backup whichever is the more recent, so this box is left clear.

Advanced parameters

If it is necessary to set a parameter before running the backup opera-

tion, click on , enter

the parameter and its value and add it to the list. This is sometimes required when using Arkeia plugins to make hot backups. We had no parameters to set, so we clicked on

to continue creating the backup configuration.

In the next screen, we double-clicked on the client computer displayed in the list, and drilled down by double-clicking through the directory tree to find the data we wanted to include in this backup configuration.

In this screen, we added the data to be backed up, by clicking on the directory to highlight it, then clicking on

. We could have selected individual files from directories in the same way.

We clicked on to

save the backup configura- tion. Arkeia Smart Backup then logged a new tape, giv- ing it a name based on the backup configuration: sports_centre_total_Tape_1.

Note that this time, we were not asked if we wanted the backup to start immediately, because it is a scheduled periodic backup.

After clicking OK in the new tape notifica- tion, the Backups management screen listed the backup configuration, and its creation date (mm/dd/yy format).

When the total backup job we have just created first runs, Arkeia Smart Backup will select an unused tape in the tape library, label it sports_centre_total Tape 1, insert it into the drive and start the backup job. If the tape is filled before the backup job is completed, a second tape will be selected from unused tapes in the library, labeled then inserted, and the backup job will continue.

A new tape will be requested for the first backup at each change in level. In our example, a new tape will be used for the first weekly total backup job, and for each new weekly total backup job. The same applies to the daily incremental backups.
