The archiver automates storage management operations by using information in the archiver.cmd file. Before writing this file, review the following general guidelines:
Save your archive logs The archive logs are essential to recovering data even if the SAM software is unavailable. Keep these logs in a safe place in the event of a catastrophic disaster.
Use regular expressions for volume ranges Enable the system to put files on many different volumes. Volume ranges allow the system to run continuously. If you use specific volume names, the archive set copies can fill a volume rapidly, which can cause workflow problems as you replace media.
Set an optimal archive interval The archive interval is the time between file system scans. Set your archive interval based on how often files are created and modified, and whether you want to save all modified copies. An archive interval that is too short keeps the archiver scanning almost continuously.
Consider the number of file systems you are using. Multiple file systems increase the performance of the archiver over a single file system. Multiple file systems can be scanned in less time than a single file system.
Use directory structures to organize your files in a file system To maximize performance, do not place more than 10,000 files in a directory.
Always make a minimum of two file copies on two separate volumes Putting data on a single media type puts your data at risk if physical problems with the media occur.
Back up your metadata (directory structure, file names, and so on) Use samfsdump on a regular basis. The metadata is stored in an archive set that has the same name as the file system. You can use this information to recover a file system in the event of a disaster. If you do not want the archiver to back up your metadata, set archivemeta=off in the archiver.cmd file and schedule the samfsdump command to run in a cron file.
These guidelines can improve the performance of your file system and the archiver, which ensures that your data is stored in the safest possible way.
