Configuring PostgreSQL Database Backups
Step 1: Adding Basic Job Details
Enter the following details;
Backup Job Name: Provide any proper name for your backup job.
Backup Repository: Select the backup repository type. You can choose either Block Storage or Object Storage.
Repository Name: Once selecting the repository type, use the drop-down list to select the repository for your backup job.
Immutable Backups (Only for Object Storage):
- You have the option to enable this feature by checking the box, which will secure your backups as immutable for a specific duration. The duration can be specified and you do it for up to 999 day(s). The duration set will be applied to this backup job, which you’ll configure in subsequent steps. When configuring other backup jobs, ensure to adjust the duration according to your needs.
- Immutable backup in the BDRSuite Backup Server is a backup strategy or system you can use where once the data is backed up, it cannot be edited, deleted, or tampered with until a predefined time period expires that can be set up as shown below in the image representation. This approach adds an extra layer of protection to the backup data, making it resistant to ransomware attacks, accidental or malicious changes
Job Description: Provide a job description for future reference.
Step 2: Database Selection
The database selection begins by listing the added PostgreSQL databases, each of which can be expanded to select the specific PostgreSQL servers for backup. After the selection is complete, the chosen databases and servers for backup will be displayed in a table on the right-hand side of the page for your reference.
Select the required PostgreSQL Server to proceed to next step.
Step 3: Scheduling
The schedule option defines the frequency of your PSQL Backup job.
Incremental Backup Schedule
You can configure the incremental backup schedules by choosing between Run Every/Run Daily/Run Weekly options.
Select Run Every option if you want to run your backup at regular intervals on a specific day(s). The time frame ranges from 15 minutes to 12 hours a day on specific days a week. By default, all the days in the week will be selected. If you don’t want to run your backup on all days, manually select the days on which you want to run the backup.
If you want to run your backup every day, select the Run Daily option and configure the period in which your backup has to occur.
If you want to run your backup every week on a specific day and time, choose the Run Weekly option. Select the time frame and day in which you want to run the backup.
Note: By default, Run Every option will be selected for the backup schedule.
Additional Full Backup Schedule
In some cases, you may require to create a periodic full backup weekly or monthly, or quarterly basis to adhere to your organization policy. Also, it is not a best practice to configure a backup job with one full backup followed by forever incremental backups. BDRSuite’s Additional full backup option allows you to comply with your requirements by creating a full backup periodically.
The additional full backup resets a backup chain and the subsequent incremental are based on the recent full backup. Running additional full backups frequently may sometimes lead to storage space consumption, you can automatically delete the older full backups chain by setting the appropriate retention policy for the additional full backups or deleting it manually when required.
Enable the additional full backup by toggling the slider to the right. Once enabled you will have to specify the scheduling for the synthetic merge to happen.
Specify the Additional full backup frequency. You can specify to run the additional full backups on a weekly or monthly basis.
- If you have scheduled the incremental backups to run Every Few Hours/Min or Daily or After Backup, then you can set the additional full backups frequency as Daily or Weekly or Monthly.
- If you have scheduled the incremental backups to run Weekly or Monthly, then you can set the additional full backups to run on a Weekly or Monthly basis.
Additional full backups are disabled Manually & One Time backup schedules
- If you are selecting the additional full backups to run on a daily basis, then you have to select the start time to run the additional full backups.
- If you are selecting the additional full backups to run on a weekly basis, then you have to select a day and start time to run the synthetic merge. You can select one or more days in a week to run the additional full backups.
- If you are selecting the additional full backups to happen on a monthly basis, then you have to select the month, select a day in the month and start time to run the additional full backups. You can select one or more months in a year to run the additional full backups.
Advanced Schedule Settings
The Advanced Schedule Settings allow you to specify the Backup Window time and Backup Validity for your backup job.
Backup Window: If you don’t want the backup run at a specific time interval, then you can specify it in the backup time window. The backup window prevents the backup job from running during peak production hours and ensures there is no unwanted overhead in the production environment. Select one of the available options to set up the backup window for your backup job
Use Global Settings: Selecting the‘ Use Global Settings’ option will apply the Backup Window setting of your backup server to this backup job. You can set up the global backup window settings for your entire backup server at Backup > Configure Backup Settings > Backup Window.
In case, if you are selecting the ‘Use Global Settings’, but if global backup window settings are disabled for your backup server, then the job will run as per its schedule
If you are modifying the Global Backup Windows settings later, it will affect all the backup jobs that are selected with ‘Use Global Settings’
Use Custom Settings: On selecting ‘Use Custom settings’, you have to specify the start time and end time for the window. The backup job will not during the selected time interval. You can also specify the applicable days for the backup window settings such as Mon-Fri or All days. Selecting the ‘Use Custom settings’ will override the global backup window settings.
No Preferences: Selecting ‘No Preferences’ will override the global backup window settings and the backup job will run as per the schedule.
Backup Validity
Set the validity for your backup job by specifying the start date and the expiration date. The Backup job will start to run only after the start date.
If you want a backup job to start to run later, for example, 5 days later from the day you have created the backup job, then you can specify the start date of the backup job accordingly. The expiry date is optional for a backup job, if the expiry date is set the incremental backup or additional full backup does not proceed after that.
