Hi Nicholas, It depends on the requirement. Is it to be able to reproduce a database at any point in the last five years, or to be able to produce a point-in-time copy at some point near to the desired time? If its "near to" they want, what is the granularity needed?
To be able to do the point in time you will need to keep all of the weekly backps and all of the incremetals and all of the transaction logs. Thats 190GB * 52 * 5 = 50 TB in weeklies alone, let alone all the rest and with no allowance for growth. The alternative is to run a separate periodic cycle (possibly monthly or bi-monthly). This could be to another TSM node as a domino backup with all the extra baggage that entails, or it could be an archive of the domino data from the OS client - this has implications for open files and may require you to shut down domino while the backup happens to ensure a clean one - however it is more flexible in that you could keep, say, weekly backups for six months and the first one of every month for the full five years or some similar scheme. Realistically though I doubt that you will ever do a restore. This sounds like either a dumb legal requirement or someone intent on *ss-covering without thought to cost or practicality. Cost it in full, don't skimp or economise in your calculations, and don't forget the administrative overhead, then let management decide if it is worth it to them. Oh, and build in some fat so that when they come back and ask you to reconsider because its too expensive, you can give them a 10% reduction fairly easily. Regards Steve.

Hi to all I am using TDP for Lotus Notes 5.1.5 for backing up Lotus Domino (size 190GB) onto 3590 cartridges. I use the following backup strategy: Lotus Domino is using Archive Logging. Perform weekly selective backups (size 190GB) of all logged databases, every Saturday Archive the transanction log frequently each day (every 4 hours) Run incremental backups every night to backup logged databases that their DBIID has changed Run the inactivatelogs command in order to expire non-essential transaction log files. I am running this command after the full backup. How can i setup the backup copy group in order to be able to restore a database 5 years old (keep backups for 5 years)? Thanks in advance Nicolas Savva
