Invest in the faster, higher-capacity components that can serve your needs beyond the present. It demonstrates this further with an example based upon using compressed or uncompressed tape capacity. Also, the type of data that is involved may well have a bearing on this depending on its compressibility. View solution in original post. I like you Andy, that's a second greta answer you've given to my posts. Communities View more.
Turn on suggestions. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. You also need to consider bandwidth use and the kind of internet connection you have — if you have 1TB of changes each day, an ADSL connection will not be sufficient to send all of that data offsite each day, regardless of how much WAN acceleration and compression you deploy!
Speed Typically Disk-Based solutions will be your fastest solution, so if you have data changing throughout the day for example, on a busy file server then you might back several times throughout the day without noticing any issues. Similarly, cloud backup can be as quick with a fast internet connection upload speed is important here.
However, tape is no slouch — looking at our own email summaries from a production backup server we maintain, an LTO tape drive backed up 1. For this particular client, they send a full backup of all of their data to tape every day. Not bad in just 3 hours. LTO drives also typically have built-in hardware encryption capabilities, to speed up the process. A cloud-based system will hold your data for as long as you pay for the storage. You could also do all of the above, in order to achieve better DR planning, long term archiving and more options should you need them.
Son tapes can be stored onsite or offsite depending on the volume of data changes. Adding up the tapes you will have: 4 son tapes assuming a five day work week , 3 father tapes and a new grandfather tape every month. Companies use the son tapes for daily backup, father tapes for weekly storage, and grandfather tapes for monthly archival.
Many companies opt for permanent storage on a quarterly or yearly basis with the grandfather tapes. The six-tape rotation method involves six different tapes used for each day of the week.
Many small businesses that do not need to backup high volumes of data use this type of tape rotation schedule. It usually consists of using four tapes for incremental and differential backups between Monday and Thursday. This scheme is the easier to implement but lacks the redundancy of a GFS tape rotation scheme.
It is best used by small business with limited data needs. The system works like this:. The Tower of Hanoi rotation method involves full backup rotation using five separate tape sets. Many companies avoid this method due to its complexity. This method offers greater security and flexibility for full backup sessions on a nightly, weekly, and monthly basis.
If you implement this scheme it is wise to have automated reminders to help everyone keep track of what tape is to be used each day. Tape has been one of the primary storage media resources since the s.
Over time, however, tape drives have become overshadowed by disk and cloud storages due to the growing demands of data-driven businesses. As a result, people started to believe that the rise of disk and cloud storage meant the death of tape.
Other popular misconceptions about tape as well as backup to tape include poor performance, low capacity, and no scalability. This blog post describes the most popular tape backup myths and attempts to debunk them. Moreover, we will focus on the current state of the tape as a backup medium and where the backup to tape technology is heading in With this functionality, you can send full and incremental data backups to tape as well as manage multiple tape libraries from a single pane of glass.
Read further to learn more. Before we can delve into the most popular misconceptions about tape backup, we should first understand what magnetic tape backup is and how it works. Magnetic tape backup is a data protection approach, which entails storing digital data on tape cartridges or cassettes. By copying data to a tape cartridge, you can ensure stable data archiving and full recovery of necessary information, should your primary backups get damaged or corrupted.
Tape was the primary way of storing digital data from the s through mids — up to the point when hard disks became more widespread as they could offer a lower price, higher capacity, and better usability than magnetic tapes. These characteristics made hard drives an effective alternative to tape backups. Nevertheless, tape drive backup still remains one of the main options for storing data due to the large storage capacity, lucrative cost per unit, and reliability that magnetic tapes can offer.
However, magnetic tape has its disadvantages as well. For example, for the purpose of reading or writing digital data onto a tape, you should use a tape drive. Note that tape drives are sequential-access devices, meaning that in order to access a specific data block, you first need to read all the preceding data blocks. Also, tape cartridges and cassettes can deteriorate over time if kept in unfavorable conditions, resulting in unwanted data loss.
As you can see, tape backup has been around for several decades. Even with the emergence of new and more advanced storage media, businesses did not stop performing tape backups.
