| Companies need to explore data deduplication as a | | | | type have configuration settings to adjust |
| means to cut business expenses. Backups and | | | | performance to provide for faster restores. |
| particularly remote data backup has been one of the | | | | Synonymous with the other types of software |
| most high-ticket items of a business budget. | | | | system byte-level data deduplication compares the |
| Advances can be made to processes and shrinking | | | | current data that it is processing with the bytes that |
| the budget from a successful data deduplication | | | | it has checked previously. Byte-level comparisons are |
| backup software package implementation. There are | | | | extremely precise. Many of these programs are |
| various ways that deduplication is implemented. | | | | content aware which means the software has the |
| Single instance deduplication preserves only one | | | | capability to identify the file name, file type and date |
| instance of a file no matter how many duplicates | | | | time stamp. Comparisons at byte level are resource |
| there are. Backup software package has in the past | | | | intensive therefore they are ordinarily done after the |

| one the same. Single instance deduplication one copy | | | | Backups happen promptly because they are stored |
| of identical files would be saved and all other | | | | to disk but extra time and backup storage is involved |
| instances would be maintained as pointers. This keeps | | | | to maintain them while it is being processed. Byte |
| a lot of space in the backup storage system. This | | | | level backups preserve one backup as the master |
| method also prevents the superfluous backups of | | | | ordinarily the most recent. By keeping one master |

| With block level data deduplication the files are | | | | All venders of remote data backup software |
| separated into blocks of data and then compared. | | | | packages have their own approach to data |
| Depending on the software solution the blocks to be | | | | deduplication. There are many answers to the |
