Mass Storage – Availability of Accidentally Deleted Files
Description: On an ordinary Unix/Linux file system, a file’s inodes and data are removed upon deletion. In Mass Storage, the inodes are removed; however, the data remains on tape until a “recycle” process is run. This means that any file which has been accidentally deleted, but which has had its inodes backed up and data written [...]

Mass Storage – How Do I Put Files There?
Description: Files can be moved in and out of mass storage by using simple Unix/Linux commands such as “cp” and “mv”. As the Mass Storage system is optimized for archiving data, your programs should not directly read or write from the Mass Storage system. Instead, copy your data from ~/ms to scratch space such as /netscr/<onyen> [...]

Mass Storage – Long Term Storage of Files
Description: We have chosen to implement SAM-FS as our mass storage software in part because of its non-proprietary tape format. We believe that any non-deleted file that is on Mass Storage tape will be retrievable for as long as the tape remains readable. Due to the unknown longevity of tape media, we can not guarantee how [...]
