Examples regarding the required upload times

The resulting data is stored server-side respectively in 7 day, 4 weeks and 3 months backups. The recommended memory requirements and the approximate duration of backup is shown in the following tables.

Small data sets

There is data traffic of small businesses or individuals. The bandwidth is achieved with an ADSL connection.

Data Change Bandwidth Initial Delta Backup space
1 Gigabyte 7% 100 kilobits / s 22 h 45 min 1 h 35 min 3 gigabytes
2 Gigabyte 7% 300 kbit / s 15 h 10 min 1 h 03 min 6 gigabytes
3 gigabytes 7% 500 kilobits / s 13 h 39 min 0 h 57 min 9 gigabytes
5 gigabytes 7% 1,000 kilobits / s 11 h 22 min 0 h 47 min 15 GB

Mean data sets

Here is data volume of data-intensive small businesses and medium sized businesses. The bandwidths are a sdsl connection achieved.

Data Change Bandwidth Initial Delta Backup space
10 gigabytes 6% 2 megabits / s 11 h 22 min 0 h 40 min 29 Gigabytes
20 Gigabyte 6% 4 megabits / s 11 h 22 min 0 h 40 min 57 Gigabyte
30 gigabytes 6% 4 megabits / s 17 h 04 min 1 h 01 min 86 Gigabyte
50 GB 6% 8 Megabit / s 14 h 13 min 0 h 51 min 142 GB

Large data sets

Here is data volume of data-intensive medium-sized businesses or large enterprises. The bandwidths can be achieved only via a fiber optic connection.

Data Change Bandwidth Initial Delta Backup space
100 GB 5% 20 megabits / sec 11 h 22 min 0 h 34 min 270 GB
200 GB 5% 50 megabits / sec 9 h 06 min 0 h 27 min 540 GB
300 gigabytes 5% 50 megabits / sec 13 h 39 min 0 h 40 min 810 GB
500 gigabytes 4% 100 megabits / sec 11 h 22 min 0 h 27 min 1:28 Terabyte
1 terabyte 4% 100 megabits / sec 22 h 45 min 0 h 54 min 2:56 Terabyte

Comments on the information

For the preparation of the above information was make certain assumptions. Depending on the type of data, the data can be significantly lower, it is the backup time, the required backup space, or bandwidth. The following list provides information about possible optimization potential:

  • Compression of data for transport
  • Compression of data for storage
  • Higher upload bandwidth, such as sdsl
