[S2E2] Backups Breakups

In this article, I am going to explain how we can split the large backup file into multiple small backup files using SSMS 2016. I will also explain how we can combine multiple backups to restore a database and split the backup of the SQL database using SQL Server Management Studio (SSMS).

[S2E2] Backups Breakups

Server backup is not automatically configured during installation. You should protect your server and its data automatically by scheduling daily backups. It is recommended that you maintain a daily backup plan because most organizations cannot afford to lose the data that has been created over several days.

In the default installation of Windows Server Essentials, the server is configured to automatically perform a defragmentation once each week. This can result in larger than normal backups if you use non-Microsoft imaging software. If it is not necessary to defragment the server on a regular basis, you can follow these steps to turn off the defragmentation schedule:

When you use the Set Up Server Backup Wizard or the Customize Server Backup Wizard, you can choose to back up server data at multiple times during the day. Because the wizards schedule incremental-based backups, the backups run quickly, and server performance is not significantly impacted. By default, the wizards schedule a backup to run daily at 12:00 PM and 11:00 PM. However, you can adjust the backup schedule according to the needs of your organization. You should occasionally evaluate the effectiveness of your backup plan, and change the plan as necessary.

You can use multiple external storage drives for backups, and you can rotate the drives between onsite and offsite storage locations. This can improve your disaster preparedness planning by helping you recover your data if physical damage occurs to the hardware onsite.

If you choose a drive that contains previous backups as the backup target, the wizard allows you choose if you want to keep the previous backups. If you keep the backups, the wizard does not format the drive.

The drive cannot contain an Extensible Firmware Interface (EFI) system partition. If an EFI partition is present on a USB drive, it is assumed that the disk is a startup disk. If you are certain that you don't need the data on the disk, you can reformat the disk and use it for backups.

If a backup is unsuccessful because the backup drive had insufficient space, the drive letter for the backup target drive is removed from the Windows Server Essentials database, and the Dashboard does not display the drive. If you want to use the drive in future backups, you must reassign the drive letter using a native tool.

Modern tape technology such as Linear Tape-Open 8 (LTO-8) can store up to 9 TB of data on a single tape. You can then ship the tape to a distant location, preferably at least 100 miles away from your primary location. Tape backups have been used for decades, but their obvious downside is the extremely high RTO and RPO due to the need to physically ship the tapes to and from a backup location. They also require a tape drive and an autoloader to perform backup and recovery, and this equipment is expensive.

Data archives and backups are not the same. Even though they are both used to store data, you should use them for different purposes. Data backups protect data that is currently in use. This enables you to restore corrupted or lost data from a single point in time.

Amazon ElastiCache clusters running Redis can back up their data. You can use the backup to restore a cluster or seed a new cluster. The backup consists of the cluster's metadata, along with all of the data in the cluster. All backups are written to Amazon Simple Storage Service (Amazon S3), which provides durable storage. At any time, you can restore your data by creating a new Redis cluster and populating it with data from a backup. With ElastiCache, you can manage backups using the AWS Management Console, the AWS Command Line Interface (AWS CLI), and the ElastiCache API.

Though it's rare, sometimes the backup process fails to create a backup, including final backups. Insufficient reserved memory is often the cause of backup failures. Therefore, make sure that you have sufficient reserved memory before attempting a backup. If you have insufficient memory, you can either evict some keys or increase the value of reserved-memory-percent.

Redis (cluster mode enabled) only supports taking backups on the cluster level (for the API or CLI, the replication group level). Redis (cluster mode enabled) doesn't support taking backups at the shard level (for the API or CLI, the node group level).

Using ElastiCache, you can store one backup for each active Redis cluster free of charge. Storage space for additional backups is charged at a rate of $0.085/GB per month for all AWS Regions. There are no data transfer fees for creating a backup, or for restoring data from a backup to a Redis cluster.

In versions 2.8.22 and later, Redis backups choose between two methods. If there isn't enough memory to support a forked backup, ElastiCache use a forkless method that uses cooperative background processing. If there is enough memory to support a forked save process, the same process is used as in earlier Redis versions.

To define multiple backups, in the Administration module, select Artifactory Backups. Each backup may have its own schedule and repositories to either process or exclude.

For a site administrator, automated course backups are more expensive in terms of time, CPU usage and storage. The recovery time to have a site running again takes longer than a site backup. However, teachers and site administrators might find a course backups as a way to create a "fresh" copy of a course that can be re-used (in older versions of Moodle, in newer versions see Import course data) or as a method to distribute a course(s) to other Moodle sites.

Moodle's Course backups routines are instructed to automatically skip courses based on three settings in Administration > Site administration > Courses > Backups > Automated backup setup. The Moodle administrator(s) use those settings to specify whether to Skip hidden courses (set by default to 'Yes'), Skip courses not modified since (set by default to '30 days'), and Skip courses not modified since previous backup (set by default to 'No'). A course which meets any of the enabled criteria will be skipped during the next run of Course backups.

The tar utility has a ton of options and available usage. Tar stands for tape archive and allows you to create backups using: tar, gzip, and bzip. It compresses files and directories into an archive file, known as a tarball. This command is one of the most widely-used commands for this purpose. Also, the tarball is easily movable from one server to the next.

To speed up Outlook and backup performance, I thought about splitting up my pst-file into multiple files. As data will no longer change in these pst-files, I would no longer have to include them in my daily backups.

Also make sure that you include these newly created pst-files in your backups. Of course, because you no longer add or remove data to these pst-files, you no longer have to include them in your daily backups and can therefore save yourself some time and space.

Clogged catch basins are a serious cause of flooding, which could lead to sewer backups. If you observe a clogged catch basin or one in need of repair, please call 311 or fill in this online form so our staff can track, pinpoint, and address any problem areas.

Yes, you can use AWS Backup can back up on-premises Storage Gateway volumes and VMware virtual machines, providing a common way to manage the backups of your application data both on premises and on AWS. Q: Can I use AWS Backup to access backups created by services with existing backup capabilities? Yes. Backups created using services with existing backup capabilities, such as EBS Snapshots, can be accessed using AWS Backup. Similarly, backups created by AWS Backup can be accessed using the source service. Q: How does AWS Backup work with other AWS services that have backup capabilities? AWS services offer backup features to protect your data, such as Amazon S3 Replication, Amazon EBS Snapshots, Amazon RDS snapshots, Amazon FSx backups, Amazon DynamoDB backups, and AWS Storage Gateway snapshots. All existing per-service backup capabilities remain unchanged. AWS Backup provides a common way to manage backups across AWS services both on AWS and on premises. AWS Backup is a centralized service that offers backup scheduling, retention management, and backup monitoring. AWS Backup supports existing backup functionality provided by S3, EBS, RDS, Amazon FSx, DynamoDB, and Storage Gateway. For AWS services with backup functionality built on AWS Backup, such as Amazon EFS and DynamoDB, AWS Backup provides backup management capabilities. Additional features include lifecycle policies to transition backups to a low-cost storage tier, backup storage and encryption independent from its source data, and backup access policies. Q: How does AWS Backup relate to Amazon Data Lifecycle Manager and when should I use one over the other? Amazon Data Lifecycle Manager policies and backup plans created in AWS Backup work independently from each other and provide two ways to manage EBS snapshots. Amazon Data Lifecycle Manager provides a streamlined way to manage the lifecycle of EBS resources, such as volume snapshots. Use Amazon Data Lifecycle Manager when you want to automate the creation, retention, and deletion of EBS snapshots. Use AWS Backup to manage and monitor backups across the AWS services you use, including EBS volumes, from a single place.

It is optimal to have a 1-1 relation between PV and VG. This will ensure the backups are more evenly split across the back end disks. If speed doesn't matter, add all PV to a single VG. Otherwise, create as many VG as there are PV. 041b061a72
