....after the start of the next work day. Many workstations cannot produce backup data as quickly as tapes can write [3] For example, typical backup rates (both full and incremental) on our network range between about 5 to 70 of the rated 246 KB per second of our Exabyte EXB 8200 8mm tape drives [4]. Amanda, the Advanced Maryland Automated Network Disk Archiver, was developed to solve these problems. To make the project manageable, we first built Amanda on top of the standard BSD Unix dump program. Amanda uses an optional homing disk to run multiple backups in parallel, and copies the ....

....terabyte of data in 8mm cassettes arranged in an X Y plane. Near the end of the development cycle a Metrum robot was acquired. It stores about nine terabytes of data with VHS cartridges placed around two rotating cylinders. Table 1 gives various specifications for both robots and tape readers. See [5, 4, 3, 6] for more information. While the two systems differ in detail, they have the following important 3 characteristics in common: ffl The combined latency to load a tape volume into a reader, seek to the proper location, and read a file is measured in minutes.

....On an EXB 8500 drive a single tape mark consumes 48 KB of 14 space (more than twice the size of a typical Unix file; see Table 3) so writing data in small units separated by filemarks will significantly reduce volume capacity. Filemarks on older Exabyte 8200 drives are even worse 2. 2 MB each [5]. 2 Reducing the number of filemarks also saves write time since writing a single filemark takes about two seconds on the Exabyte 8500 and eight seconds on Metrum RSP 2150. Interleaving data buffers and metadata headers is superior to placing all the metadata at the end of the tape. An ....
