(2) Native backup tools for SharePoint don't compress data. If you have a non-native SharePoint backup tool with compression capabilities, you should change this benchmark. |
| |
(3) When using native backup tools, a full SharePoint backup is needed for disaster recovery. When using Quest Recovery Manager for SharePoint along with a native backup tool, an administrator can use full backup for disaster recovery, site recovery, and single item recovery. |
| |
(4) When using native backup tools, SharePoint site backups are needed for site recovery and single item recovery. |
| |
(5) Cost of tape backup hardware - devices and media is $1.68 per GB, according to Government Information Technology Issues 2006. |
| |
(6) A standard industry benchmark for for hardware maintenance contract is 20% of hardware costs. |
| |
(7) A document recovery from SharePoint site backup takes about 4 hours with native tools. |
| |
(8) According to some corporate policies, a typical document recovery request should be completed within two working days. Although an item can be recovered with native tools from SharePoint site backup for two hours, administrators usually don't have that time during a working day and they usually have to postpone such requests to a day-end or the next day. When using Quest Recovery Manager for SharePoint, an administrator typically doesn't have to postpone single item recovery requests because they can be fulfilled just in several minutes. |
| |
(9) User productivity loss during network downtime is about 20%-25%, according to some researches. |
| |
