COMMENTS
|
|
|
(i)
Typical company's IT policy requires organization to make an Active Directory
backup every day.
|
| (ii) Total time required to ensure that a backup task is successfully executed. The only way to check the success of backup tasks (when using only native tools) is to look through the list of backup files and check the date and size of each file (at least). Recovery Manager for Active Directory generates logs which show the status of backup tasks. All that administrator have to do is simply to scroll through the corresponding log (the viewer is built-in into Recovery Manager interface) and look for errors in the same way as he does with Windows event logs.
|
| (iii) When using native tools, you have to schedule a backup task on each domain controller individually (either by visiting a DC or through a terminal session). The time needed to configure backup jobs using Recovery Manager for Active Directory cannot be done on a strictly per DC basis because the product enables you to put multiple DCs into a collection, set the configurations once, and have them applied to all DCs in the collection. Typically, it takes 30 to 60 minutes at most to configure all backup jobs using Recovery Manager for Active Directory (of course, if you have already designed the backup sytem architecture.) |
| (iv) As your network infrastructure changes, you may want to revise and reconfigure backup tasks. We assume that the changes are made once a year. You can modify this value according to your policies and expertize. |
| (v) You have to enter your value according to your experience and expertize. Based on our experience, we assume that a middle company (with up to 3000 users) may have about 2-3 network outages connected with AD object errors per year. Larger companies may have 1 such outage per 2000-user network segment. |
|
(vi) Before you restore the Directory database, you should
perform some critical operations: restore the Sytem State for NTDSUTIL
(refers to native tools) or unpack the Recovery Manager for Active Directory
backup data correspondingly.)
|
| (vii) Native tools require to restore each object individualy by typing its full path in the command line (NTDSUTIL command). It takes 3 - 6 minutes from a professional system administrator and requires a deep knowledge of AD structure. With Recovery Manager for Active Directory all you have to do is to select the directory objects to be restored and then Recovery Manager for Active Directory will automatically fix them. It takes 2-6 seconds for an individual object. |
| (viii) When using native tool, you will need to do 2 restarts (DC is rebooted once into "recovery mode" and then again into regular mode once the recovery is complete). Each restart may take about 10-15 minutes. With larger AD database, DC restart time can take longer. Recovery Manager for Active Directory does not require to restart a domain controller. |
| (ix) This is an average time required to manually re-create a deleted or corrupted AD object and re-assign all related permissions. Recovery Manager for Active Directory allows to granulary restore individual AD objects and does not require the DC to be restarted; so there is no point in such operations. |
(x) You have to enter your value according to your experience and expertize. Our assumption is given for your information only. If a domain controller state is regularly monitored, probability of an AD database failure due to hardware problems is near-zero and can be ignored in calculations. However, due to the high complexity of administrative tasks, there is a possibility of erroneous actions with AD objects (e.g. user or an entire organization unit (OU) may be deleted or incorrect properties may be set.)
This value shows the expected average number of objects affected per downtime incident due to AD administrators' error. It primarily depends on the complexity of your AD structure. It is assumed that in larger networks an average OU affected by downtime would contain more user accounts (in sub-OUs) than in smaller networks. |
| (xi) In accordance with some researches, it is assumed that average network downtime business loss (from lost transactions) in a large company is about $84000 per hour per incident with 3000 users (or $28 per user). For simplicity of calculations, it is also assumed that there is direct dependence between average number of affected users per downtime incident and downtime business losses.
|
(xii) According to some surveys, the annual average network outages among
Fortune 1000 companies start from $3-$3.5m (excluding the cost of lost
employee productivity) and up to $32.7m (or 2% of annual revenue) in lost
revenue and productivity.
Downtime losses from poorly managed networks (99% availability) may result
in $247m per year.
