service startup after restore   
Hi there,
We have exchange 5.5 running windows 2000 server.
Do you know approximatelly how long will take for the service to start for a
200 users exchange server, after restoring the info store and directory
services from backup and starting exchange services?
We are doing full exchange databases(information store and exchange
directory) backups with Veritas 10d with exchange option.
Thanks a lot, Calin

Re: service startup after restore   
This is almost impossible to answer.
It is the size of the database and the amount of restored and/or outstanding 
transaction logs that will determine the amount of time taken to start the 
IS.
How many log files will you have to replay after the restore? Thsi will help 
give you an idea of how long it will take

Re: service startup after restore   
Hi Simon,
How can I see how many logs I have?
Let us say for example I will have 200 users. Is it one log per user? Thanks
a lot, Calin

Re: service startup after restore   
Sorry if I am not answering your question here but what exactly are you 
attempting to do?
Planning a backup/restore/disaster recovery strategy requires a good working 
knowledge of Exchange.
I do not mean to be condescending in any way but judging by your responses I 
suspect that you may require a little help with this.
I would suggest that you try and get some help from a local consultancy that 
have solid Exchange skills. An investment with a consultant seems like a 
small price to pay compared to the cost of data loss for your company. Bear 
in mind that Microsoft no longer have support for this product.

Re: service startup after restore   
Hi Simon,
    Thanks a lot. I am involved only in the disaster recovery of exchange,
we have an aexchange administrator for managing servers, we are using
Veritas 10 and was wondering the following:
-any good products for exchange 5.5 disaster recovery, to be able to recover
in shorter amounts of time including Microsoft articles
-how exchange flushes logs, and if it is possible to do it manually to avoid
logs replay after IS restore
-if logs are proportioanl with amount of data as well, I understand they are
directly related to number of users
-how can I check number of logs
If you can answer all these I will really appreciate it.
Thanks, Calin

Re: service startup after restore

All you need is a Full Exchange database backup. You can then restore the 
database up to point of failure.


-how exchange flushes logs, and if it is possible to do it manually to avoid
logs replay after IS restore

Exchange will flush the t-logs after a full online backup. Do not interfere 
with the log files manually.


-if logs are proportioanl with amount of data as well, I understand they are
directly related to number of users

Transaction logs are not directly related to the amount of users. 
Transaction logs are a record of all database operations in any given 
period. Any database operation is considered a transaction so you cannot 
directly link the amount of data in the t-logs with the amount of data in 
the DB. (For example multiple update operations on a certain page in the DB 
will not result in a proportionate DB growth)


Whay don't your company focus its resources and time on getting onto a 
platform that is fully supported by Microsoft instead of wasting time in 
devising complex Exchange 5.5 disaster recovery plans?

/Simon

Re: service startup after restore   
Hi Simon,
Thanks a lot for all your help. Main problem we still have NT4 domains and
newer versions of Exchange require active directory. Definitelly will
recommend upgrading to Ad and Ex2003 as soon as possible.
