Backup Strategy

Enabling DAOS servers will have benefits related to disk space savings and reduced I/O demands.

However, it will also introduce another level of complexity to your backup / restore planning.

Key elements are already described in the DAOS pages.

Beside the technical changes in how to do back up and how to restore, Domino administrators will have to

raise the question if the pre8.5 backup strategy will still be good to go with.

DAOS Strategy

Files in the DAOS repository will never be changed – so it is enough to perform a full backup and from this

point onwards taking incremental backups only. This sounds like great potential for saving the number of

tapes you need for your backup. Keep in mind that the main purpose for doing a backup is the capability to

be able to restore the data in case of a problem. If you have to rebuild your server from scratch, (for

example, because of a HW failure), you will find yourself waiting for incremental restores to be applied.

Although Domino itself can be up and running during that time, users wont be able to access all of their file

attachments as they have not been fully restored yet.

A definite guide for most efficient backup / restore in your environment cant be provided because the variety

of backup software on the market is too large. Also the backup/restore throughput highly influences the

optimal configuration.

With our exploration we found taking a full backup of the DAOS repository once per month and taking

incremental backups daily provides a good balance for typical customers.

Still we highly recommend to perform backup and restore tests for your environment in order to verify and

validate all aspects of your backup / restore strategy.

NSF Strategy

Due to the fact that introducing DAOS (plus other new features) will significantly reduce the size of your NSF

files, the sizing of your backup environment needs to be reviewed.

Taking NSF backups will most likely be completed in 30% (or less) of the time it took before. If you are

running a shared backup environment (for example, TSM), please review your resource allocation to re-

assign tape drive assignments that you might not need any longer.

Transaction Log Backup

Transaction Logs (in archive mode) need to be backed up. The introduction of Domino 8.5 wont change the

existing backup configuration.

Unattended Domino Server Installation

When installing Lotus Domino on a larger number of servers, you may want to use an unattended setup

routine to speed your deployment. This section provides the details you need to know to install Domino

servers automatically on Windows operating systems.

Create a new folder (for example, C:\Install85 ) on the target server, and copy the following files to this new

folder
