Hi! I use amanda on a solaris 7 box with a DTL drive (20 GB) attached. My dumpcyle is 4 weeks with 20 runs per cycle.
Because the size of one incremental backup is only between 2-4 GB I don't want to change the tape each day. Fortunately, I have a 30GB harddisk available for use as holding disk. I thought of splitting this disk into two partitions, one with 20GB and one with 10GB, writing to the first until it's full. If the first partition is full, I want the system to write that nights incremental to the 10GB partition and saving the 20GB partition to tape. After this the data on the first partition should be deleted, the data on the second partition should be copied to the first and so on. My questions are: - How can I tell amanda to write the first holding disk (the 20GB one) to tape if it is full? - can I move the data from holding disk 2 to holding disk 1 without confusing amanda? Or is there an easier way available to write this 20 GB tapes full without losing an incremental backup ( as far as I understood amanda I would lose a incremental backup if using the above strategy with just one 20GB holding disk the night the disk gets full )? Thanks is advance for your comments, Martin
