A few weeks ago, I wrote about how large the IFS (Integrated File System) is getting on some IBM i servers. To refresh, the IFS is basically a directory system in IBM i disk space that lets you store data in UNIX and Windows formats. You’ll usually find data from applications such as SAP, EnterpriseOne, and Movex Enterprise Resource Planning. You’ll also find data stored in Windows formats such as PDF, XLS, GIF, and JPG.
As the IFS has grown on your server, it’s become a significant part of your backup and recovery plans because it takes longer and longer to back up and restore. If you want to speed things up, you need to split up the backups. But, for the typical IBM i administrator, this can be tough because IFS backups and restores don’t use the same syntax as traditional library backups.
