Backup and Disaster Recovery
Cloud Backup: SNS Infotech provides Cloud Backup facility, also known as online backup, is a strategy for backing up data that involves sending a copy of the data over a proprietary or public network to an off-site server.
The server is usually hosted by a third-party service provider, which charges the backup customer a fee based on capacity, bandwidth or number of users. Implementing cloud data backup can help bolster an organization’s data protection strategy without increasing the workload on information technology staff.
How Cloud Backup works?
The backup process copies data and stores it on different media or another storage system for easy access in the event of a recovery situation. Cloud backup serves this purpose for many organizations.
There are various options for Cloud Backup:
- Backing up directly to the public cloud. The method entails writing data directly to cloud infrastructure providers, such as Microsoft Azure.
- Backing up to a service provider. An organization writes data to a cloud service provider with backup services in a managed data center.
- Cloud-to-cloud backup. For data that lives in the cloud in software as a service (SaaS) applications, this practice copies that data to another cloud.
In the process, the initial backup can sometimes take days to finish uploading over a network due to the volume of data to be transferred. A technique called cloud seeding enables a cloud backup vendor to send a storage device, such as a disk drive or tape cartridge, to the organization, which then backs up data locally and sends the device back to the provider. That removes the need to send the initial data over the network to the backup provider. After the initial seeding, only changed data is backed up over the network.
Online backup systems are typically built around a client software application that runs on a schedule determined by the purchased level of service. If the customer has contracted for daily backups, for instance, the application collects, compresses, encrypts and transfers data to the cloud service provider’s servers every 24 hours. To reduce the amount of bandwidth consumed and the time it takes to transfer files, the service provider might only provide incremental backups after the initial full backup.
Cloud backup services often include the software and hardware necessary to protect an organization’s data, including applications for Exchange and SQL Server.
A major benefit of using cloud backup is that it can make managing a backup system easier. Data moved offsite should be deduplicated to speed the backup and encrypted for protection. The service provider can use an initial seeding option to speed up the first online backup. Seeding works by placing the initial backup on an appliance and sending it to the provider to upload. After that, only incremental changes get backed up to the cloud. Customers can use their own backup software and hardware for the first step, or use an appliance and software supplied by a service provider.
SNS Infotech provides the facility of Endpoint backup solutions to transmit information of data centers for safekeeping, while it also remains accessible to end users. Backup can take on external hard drive or tape storage, but Instead of that cloud backup sends data to a secure offsite facility which ensures that the data is protected from an accident or disaster. Endpoint backup solutions usually run on a schedule, it might be every 24 hours, or it may provide continuous backup. Cloud backup solutions may detect changes, and backup incrementally to save bandwidth.
Endpoint backup is inexpensive which become very popular among Small Scale and Large Scale businesses.
Some of the features of Endpoint Backup:
- Policy Controlled Backup
- Backup Portal with Admin Console
- Ability to track the IP addresses and geo-locations of every device
- Ability to monitor and compare the state of backups
- Recover/restore data from multiple points in time
- Real-time change detection for monitored files and folders
- Option for managed hosting or own-hosting of data center backup
- Global deduplication / data compression
- Protection from malware & data loss
- Web and mobile access to files and versions
- Global endpoint location tracking (e.g. for mobile endpoints)
- Efficient endpoint backup over WAN without the need of VPN
- Powerful “exclude” and “include” file and folder filters
- Reports, alerts and notifications
Database backup is the process of backing up the operational state, architecture and stored data of database software which enables the creation of a duplicate instance or copy of a database in case the primary database crashes, is corrupted or is lost.
Database backup is a way to protect and restore a database. It is performed through database replication and can be done for a database or a database server. Database backup is performed by the RDBMS or similar database management software. Database administrators can use the database backup copy to restore the database to its operational state along with its data and logs. The database backup can be stored locally or on a backup server.
Types of Database Backups:
Normal or Full Backups: In this backup type all the files on that drive are backed up i.e. system files, application files, user data — everything. Those files are then copied to the selected destination (backup tapes, a secondary drive or the cloud), and all the archive bits are then cleared. This is the fastest resource to restore the lost data because all data saved in a one location.
Incremental Backups: Incremental Backups grab only those files that have been updated since the last normal backup. Once the incremental backup has run, that file will not be backed up again unless it changes or during the next full backup. While incremental database backups do run faster, the recovery process is a bit more complicated.
Differential Backups: This is alternative backup system to Incremental Backups. This is low complicated restoration process. Incremental Backups grab only files that have been updated since the last normal backup, however, differential backups do not clear the archive bit.
It starts with a full backup and subsequent backups only contain data that has changed. The difference is that while an incremental backup only includes the data that has changed since the previous backup, a differential backup contains all of the data that has changed since the last full backup.
Synthetic Full Backup: A synthetic full backup is a variation of an incremental backup. Like any other incremental backup, the actual backup process involves taking a full backup, followed by a series of incremental backups. But synthetic backups take things one step further. Synthetic backup different from an incremental backup is that the backup server actually produces full backups.The primary advantage of a synthetic full backup is a greatly reduced restore time. Restoring a synthetic full backup doesn’t require the backup operator to restore multiple tape or disk sets. Synthetic full backups provide all of the advantages of a true full backup, but offer the decreased backup times and bandwidth usage of an incremental backup.
Incremental Forever Backup: Incremental-forever backups are often used by disk-to-disk-to-tape backup systems. The backup server typically stores all of the backup sets on either a large disk array or in a tape library. It automates the restoration process so that you don’t have to figure out which tape sets need to be restored. The basic idea is that, like an incremental backup, an incremental-forever backup begins by taking a full backup of the data set. After that point, only incremental backups are performed.
