Restoring Data

At what point is the data available for restore? The data is available for restore immediately after it has been backed up and is held offsite.    Can an individual file or registry be restored? Yes, you can restore an individual file or registry and also specify which version you want to restore.    Can DASB perform bare-metal restores? Assuming that the machine in question has had a full backup of all files and registry and the data is being restored to a machine of similar hardware, then a full disaster recovery of that machine is very simple.    After installing the operating system, there is no need to apply service packs, configure domain security or install additional software to the new machine, as all this information will be included in the restore.    Can you restore a whole backup set to a point in time, e.g. last Monday? Yes, DASB will display all the files that were backed up on any given day. Providing the backed up files have not been deleted by an administrator or overwritten by more recent versions, then it is possible to restore from any given date.    How quickly will data restore over the leased line? A T1 will restore at approximately 200K / sec, however, this data is compressed, bringing the effective restore speed to nearer 400K / sec. Additionally, as all the data is held offsite on disk, the access time for the data is virtually nil. A traditional tape restore scenario may take at least half an hour to locate, insert and catalogue the tape.    What if the connection is congested with backup data? The connection is bi-directional, the restore data is transmitted down the line, whilst backup data transmits up the line. There will be very little, if any, conflict between the two. Typically backups occur 'out of office hours' while restores are required during the working day, however it is possible to perform both restores and backups simultaneously if desired.    What happens if the file or group of files to be restored is too large, i.e. it will take too long to transfer back to the DS-Client Backup Appliance? A threshold point will have been agreed, whereby the time taken for a specified amount of data to be restored down the wire, will take longer than it would for DataAssure to remove it from the Data Center and transport the disks manually to your site.    If this threshold is reached, DataAssure will ship the data direct to your site and restore at LAN speeds. This threshold depends on the amount of data to transmit and the bandwidth of line installed.    Can data be restored to a different machine on our network? Yes, the restore data can be redirected as desired. You are able to browse the network and provide connection credentials for the redirected restore, just as you do for creating the initial backup set.
