SnapManager provides two ways for you to start or schedule a transaction log backup: using the SnapManager Backup Wizard or using the Backup and Verification tab. See the following topics for more information:
Note
The topics in this section describe how to start or schedule a SnapManager backup of SQL Server transaction logs only. If you want to back up transaction logs as a follow-on task to a successful full database backup, see Creating a full database backup using SnapManager.
A backup of only transaction logs is specified using a combination of parameters.
Each time you start or schedule a transaction log only backup, you must specify the following information in either the Backup and Verification tab or in the Backup Wizard:
When you select one database, SnapManager automatically selects all other databases that are located on the same Data ONTAP storage volume. You can deselect databases that reside on a different LUN from the database(s) you selected, even if the LUN is on the same storage volume.
When you select databases at the SQL Server instance level and one of the selected databases cannot be backed up for an unexpected reason (such as the database being offline or in a loading state at the time of the backup), the transaction-log-only backup operation will progress as follows:
If the databases on the LUNs on Data ONTAP storage volumes are moved to local disk at later time, the previously scheduled backup operation will skip backup deletion. In this case, the backup operation will need to be re-created and rescheduled in order for backup deletion to proceed for future operations.
Note
For an instance-level full database backup operation in which one of the selected databases cannot be backed up, the operation will proceed in the same manner as described above.
For a description of this option, see Automatic deletion of the oldest backups in a management group.
This feature is typically used to archive the backup, as described in Automatically archiving SnapManager backups using SnapVault.
For more information about this option, see Replicating Backups to Mirrored Volumes.
Note
If you want to schedule the backup to run later, you also need to know the job scheduling information.
The following list summarizes the backup settings that pertain to transaction log only backups. These settings enable tasks that can be performed after the transaction log backup finishes successfully.
Selecting this option enables you to manage the number of SnapInfo Snapshot copies.
Selecting this option enables you to manage the size of the transaction log.
The preceding options are configured using the Transaction Log Backup tab of the Backup Settings dialog box, described in Configuring the profile of a transaction log backup.
The Backup Settings dialog box can be accessed from the Backup and Verification tab, as well as from the Backup Wizard.
For more details, see Configuring the profile of a transaction log backup.
To start or schedule a backup of only transaction logs using the Backup and Verification tab, complete the following steps. If you want to automatically back up transaction logs after a full database backup is finished, see Creating a full database backup using SnapManager instead.
