Backup Challenges for Enterprises
Don't know how to assess a suitable backup solution
There are various backup solutions on the market, and the factors to be considered are complex, which make it difficult to judge
Trial and error costs caused by the absence of experience
Organizational IT personnel have no professional backup knowledge and experience, which may cause setting errors and restore failures
Enormous cost and workload for backup operations
Save the total cost of backup investment and enhance data protection through backup modernization
Common Backup Myths
Only local backup, no off-site backup
It cannot be remedied when encounter a major unexpectable disaster, such as earthquakes, fires, power shortage and human error.
No consideration of the maximum amount of data loss (RPO)
It may lead to the loss of important data, and it may be necessary to spend high costs to rebuild the data.
Put internal shared data and backup data on the same device
If the hardware is damaged, all data will be lost, which is equivalent to putting eggs in the same basket.
Use off-site/cloud backup to make up for the shortcomings of pure local end
Enterprises do not need to invest in and maintain hardware, and can complete deployment in a relatively short period of time, greatly reducing construction and management costs.
Consider RTO and RPO for your business
RTO is the abbreviation of Recovery Time Objective, which refers to how long the enterprise plans to restore the service to normal after the accident occurs. RPO is the abbreviation of Recovery Point Objective, which refers to the time point of the latest backup by the enterprise at the time of the accident, that is, how much data the enterprise can tolerate loss.
Follow the 3-2-1 principle for back-up
According to the 321 principle, there must be 3 copies of files stored in 2 different forms, and 1 copy is off site. For example, if a file has two backups, one on a traditional hard disk and the other on a NAS, and the location of the NAS is different from that of the traditional hard disk, it complies with the 321 backup principle.
Local / Off-site Backup
With expertise in local/off-site backup, we can help you customize and plan the most suitable backup solution for your enterprise while assisting with the daily maintenance workload.
Assist in the construction of servers/storage devices off site to store data, connect the two networks, provide real-time operation functions, and maintain continuous service.
Disaster Recovery as a Service (DRaaS)
DR service focuse on the recovering speed to maintain uninterrupted business, which is in line with investment benefits and truly realizes "Always-on Business".
Backup Recovery Test
Use disaster drills to verify backup availability, confirm service recovery time and system recovery sequence, and enterprises can formulate SOPs for disasters on this basis.
How to find the best backup method for your business?
Formulate according to business operation and risk control goals
- RTO/RPO: RTO (Recovery Time Objective): How long can the enterprise tolerate the downtime? ; RPO (Recovery Point Objective): how much data loss can be tolerated at most?
And classify data by importance
- Hot data vs cold data: cold data refers to the important but infrequently used data, which is not expected to be accessed within 30 days; hot data refers to the important and commonly used data, which is recently frequently accessed.
Confirm what needs to be backed up, and usually distinguish between full-computer backup and data backup.
- Full-system backup: pack up with the operating system and applications for backup
- Data backup: only back up data, such as backing up database files, C disk, and certain files of the file server.
After selecting the data, start to decide the backup method.
- Full backup: back up all the target data every time
- Incremental backup: back up the addition of the previous backup file
- Differential backup: back up the difference between the backup and the previous "full backup".
After the decision is made, where should the data be backed up?
- Local backup: the backup data is stored in the same computer, but when the local hard disk is damaged, neither the original data nor the backup data can be retrieved. Therefore, local backup is not suitable to be used as the main data backup method.
- Remote backup: to avoid the risk of simultaneous damage to the original data and the backup data, store the backup data on a different machine (it can be another computer or an external hard disk). For example, the server data in the company's computer room is backed up to the NAS in the computer room without leaving the intranet.
- Off-site Replication: For example, the server data in the computer room of the Taipei head office is backed up to the NAS in the computer room of the Taichung branch: a VPN is needed to connect the two networks.
- Cloud backup: Back up data in the local to the cloud, eliminating the off-site cost and complexity.
- 3-2-1 backup principle: 3 copies of backup data, 2 storage media (commonly two NAS or 1 cloud and 1 local), 1 copy off site (commonly backed up to the cloud or to the IDC computer room or branch office)
Hand it over to the Freedom Systems for one-stop backup solution
Assess the company's operating priorities and information environment, plan and deploy software and cloud configurations
Execute backup scheduling based on enterprise data aging requirements, backup targets, network architecture, etc.
Monitoring and Operation
Execute backup mechanism setting and monitoring and adjustment, and the technical maintenance team regularly manages the backup
Implement scheduled recovery drills, disaster immediate response recovery, and environmental adjustment consulting
Backup is to copy the data you want to protect, so that you have a backup file of the target data; replication is to copy the important IT system of the enterprise in different geographical locations (off-site) for backup, in case of emergency, IT systems can be switched for backup to maintain business operations and reduce the impact of disasters.
Before setting the backup frequency, three factors need to be considered: 1. How often data is updated; 2. RPO and RTO; 3. Storage space.
If the update frequency is low, but the backup frequency is set to be high, there will often be situations where backups are required without updating, resulting in a waste of backup space or resources; relatively, the data update frequency is high, but the backup frequency is low, there will be situations where backup updates version will be missed; when the data no longer changes, the data can be moved out of the scope of continuous dynamic backup.
Before formulating the retention period, you need to consider 1. Whether there is a need for review or re-examination of the data (version retrospective or audit requirements); 2. RPO; 3. Factors, such as the size of the backup space. If the data is no longer changed or there is no need for re-examination, then it is enough to maintain the latest backup. Only when you are not sure whether there is a need for review, it is suitable to set the retention period according to the available backup space.
