C-ISAM and backups
C-ISAM on UNIX We want to implement a structured backup system for some UNIX servers which contains some C-ISAM "databases". Aside from considering the Open File Manager functionality - "enterprise-class software that enables your backup application to also back up open and in-use files, ensuring business continuity and protection of mission-critical data" - are there any other considerations for backing up C-ISAM systems? thanks -- Neil Truby t:01932 724027 Director m:07798 811708 Ardenta Limited e:neil.truby@ardenta.com

NOTEif a file is open and someone has started a trx, then restore will need transaction data!!!!!!!!! since it sounds like a moving target, the backup you'll create will be or sounds like the same as creating an IDS backup using dd without blocking the server.....
