Without the correct technology, backup over internet can be a painful process: it can be slow and use a lot of bandwidth. Our Backup24 solution solves this problem in a very efficient way, so update-backups can also be done perfectly using lower-bandwidth technologies (older modems, GSM, GPRS, wireless, ...).
Ofcourse, for the initial backup, all your data need to be transferred to the backup-center. This can happen overnight.
The first technology applied to reduce the bandwidth is compression. Files, depending on their format, can be reduced to half of the size without losing any data (technique comparable with making a ZIP package of files to reduce the size). This speeds up the transfer.
Update backups, after the initial transfer of files, are even more efficient. Further optimisation comes from the patented DeltaBlock technology. This technology will make sure only updated parts of a file are transmitted, instead of the whole updated file as traditional backup-technologies do.
So instead of transmitting the whole MS-Outlook or MS-Access datafiles, the deltablock technology will only transmit the changed data-blocks. On top of that these blocks are then compressed, leading to a very limited use of the bandwidth.
The described Compression and Deltablock technologies assure that very low volumes are transmitted for a daily backup. A typical update backup takes not even 10 minutes over a normal internet connection.
Your internet subscription
Dialup
Dialup internet connections have no limit in the volume that can be transmitted.
Broadband internet subscriptions usually have a limit on the data that can be transmitted over the link. A little caution is needed when sending over the initial backup, to make sure your internet-transfer limit is not exceeded. We propose to select only a few directories in the "Backup view" - "Explore to pick files" for the first night, and then add directories every day until all data is transferred overnight. Once all the files are transferred, there is no more problem because of the optimisation techniques described above. Also, the data that goes over the internet line is a lot less than the size of the selected data on your harddisk, also thanks to the optimisation techniques described above.
ADSL
Usually the total allowed bandwidth is the sum of send and received data. If the limits on your subscription plan are low (eg. ADSL Light), you could check if you do not run out of available data-volume that can be transmitted (please check with your provider to find the used and available volumes for your internet-account.
Cable
The Belgian cable provider Telenet only counts nightly data-traffic for 50% towards the limit (between 0:00 and 10:00, see Nachtsurfen bij Telenet in dutch for more info). Backup24 is configured by default to perform a backup between 0:00 and 7:00, to take advantage of this rule. You can change the backup-schedule by selecting "Options" - "Backup Schedule" in the Backup24-software.

company" Carine Olssen, Vinnie -

42% of tape-restores fail
According to a study 42% of the interviewed computer users that
used tape-backups reported that they were not able to
retrieve data from their tape-backup after a data-loss.
