Comparison: Tape vs Disk Backup

Backing up your data is absolutely essential as it enables you to safeguard your valuable information from potential loss or damage. For enterprises, the absence of a backup can have severe consequences, especially when data is damaged. It not only entails the hassle of re-entering the data but also significantly hampers the enterprise's normal business development. Various methods exist for backing up data, with tape and disk backups being the most common. To help you make an informed decision regarding preventive measures, we will now outline the advantages and disadvantages of these two backup methods.

Pros and Cons of Tape vs Disk Backup

Tape Backup
Tape drive backup continues to be a popular choice for data storage because of its considerable storage capacity, cost-effectiveness, and reliability. The durability of tapes is the primary factor behind their extensive usage among large corporations. When properly maintained, tape drives can retain essential data for over 30 years, or possibly even longer. Consequently, tape backups provide the advantage of extended retention for crucial data, ensuring exceptional archival stability.

However, magnetic tape has some drawbacks. Its read and write speed is slower compared to disks and it requires sequential access, resulting in longer latency and lower throughput. Unlike hard drives, tapes do not offer random access. This means that if you need to restore a file located at the end of a tape, the drive must go through the entire tape to locate the desired file.

If you have a large amount of data, or the data is expanding rapidly, or your goal is a long-term archive and off-site storage with an infrequent need for accessing that data, tape backup can be an excellent solution. Tape provides a highly cost-effective solution for the high-density storage demands of today's multi-terabyte/petabyte environments.

磁盘备份
With disk-based data protection, backup data can be easily moved. It can be effortlessly copied over the network to offsite locations or even to the cloud, as it does not require physical media or transportation to another location. This means you can access your data anytime and anywhere. Waiting for tapes to retrieve your data is unproductive. Disk backup eliminates the time required to load a tape, search for the correct position, and locate the desired data for restoration. You can quickly recover specific files from the disk system, ensuring efficient disaster recovery. It provides immediate and random access to data storage, ensuring uninterrupted business operations. With direct access to your data, restoring lost files should be a quick, efficient, and hassle-free process. In today's highly virtualized enterprise data centers, disk-based backups have offered the speed, flexibility, and security required for organizations to effectively protect their virtual infrastructure and become more agile.

磁盘备份also has its limitations. Since the disk is constantly running, its lifespan is relatively short compared to other storage options, resulting in additional expenses for electricity, cooling, and maintenance. Moreover, there is a risk of data loss if the disk fails to start.

Tape vs Disk Backup FAQs

You may have concerns regarding the usage of tape backup and disk backup. Here are some other issues that may help you understand better. Please check them below.
1. Does tape storage degrade?
High temperatures, high humidity, and the presence of dust and corrosive elements in the air all affect the physical components that make up the magnetic tape and can result in loss of readable data through decreased magnetic capability and deterioration of the binder or backing of the tape.
2. Is disk storage less expensive than tape storage?
Both tape and disk backup technologies are cost-effective compared to higher-performance solid-state technologies. However, when comparing head-to-head on a per-TB basis, the tape is always the cheapest storage option.
3. What is the most important advantage of disk storage over tape storage?
Disk-based options offer much quicker backups and restores when compared to tape, and disk can help organizations reach their RTO and RPO goals. In the long run, consistent rapid recovery may justify a more expensive disk storage option.
4. What is the most reliable backup media?
Solid state drive (SSD) & flash drive (aka thumb drive, USB drive/stick) are the most efficient physical ways to backup your system. Flash drives and solid-state drives use flash technology to write and read data very quickly, making for speedy backups.
