A NAS storage device is an excellent backup and recovery solution. For an IT service provider, when it comes to your network-attached storage drive, or NAS, it can be difficult to decide whether to install a solid state drive (SSD) or a hard drive (HDD) to design a backup and recovery solution. Here, we'll evaluate the pros and cons of NAS with SSD versus NAS with HDD for backup.
There are a few important advantages and disadvantages in choosing NAS with SSD as a local backup for storage. These include:
Keep recent backups, not all backups on NAS. The old backups on NAS should be automatically purged. Only most recent backups are kept on NAS, saving space. This is because SSD is still more expensive than HDDs, and they also tend to be smaller, meaning they have less storage space.
However, when it comes to cloud storage, the best option tends to be NAS with HDD. If you're going to choose NAS with HDD, here's what you should know:
They aren't as fast. It should be noted that the speed of NAS with HDD is slower than SSD. However, internet speed, in conjunction with other factors, can be a major bottleneck for speed when using NAS with HDD, whereas this isn't the case with NAS with SSD.
You can get a larger size. The capacity of HDDs surpasses that of SSDs, and the capacity of HDDs continues to grow.
Conclusion: Local backup to NAS SSD and remote backup to NAS HDD
Therefore, when you design the backup solution to protect customer's data both locally and remotely, consider backup customer's server locally to NAS SSD, then replicate the backup to remote cloud NAS HDD for offsite copy. Purge the local backup aggressively to keep only needed recent backups, maintain older backups in remote cloud.
