about amanda holding disk...
Hi, Since my incremental backup is not so big(about 20G)per day. I want amanda to put daily incremental backup to the holding disk first. and then after 3 or 4 days, I flush it to one tape(100G capacity).That means the holding disk will have 3 or 4 days of incremental backup. how can I do this in configuration file or which command should I run? Another rookie question is: Currently I use Sony AIT2 50/100 tape device, each time I run amdump manually to do the backup. Now I want amanda to do it automatedly. But, Amanda automatically schedules full/incremental dumps to maintain balanced daily runtimes and tape usage, If I do a full backup each month, then the backup machine is totally down in the middle of the month, does that means the only backup I have is the backup of last month?(since this month's full backup is not finished) Thank you very much,bow...

Another rookie question is: Currently I use Sony AIT2 50/100 tape device, each time I run amdump manually to do the backup. Now I want amanda to do it automatedly. Starting with the second question. Run amdump as a cronjob or a similar thing that will let you run commands at a specific time. With this working you dont have to do anything to get your dumps to the holding disk. If you dont put a tape in the drive amdump will complain a bit and dump to the holding disk. You can then flush to tape at when appropriate. But, Amanda automatically schedules full/incremental dumps to maintain balanced daily runtimes and tape usage, If I do a full backup each month, then the backup machine is totally down in the middle of the month, does that means the only backup I have is the backup of last month?(since this month's full backup is not finished) As far as I know, No, you have what has been backed the first half of the month. Not knowing the detail I would guess that amanda gives priority to new and changed files so the damage is minimised - but others on this list will know better... Kasper
