== INTRODUCCIÓ == === Eina mt === Tret de man 4 st /dev/st* : dispositius de cinta SCSI amb autorebobinado (la cinta rebobina sola al fer el close() ) /dev/nst* : dispositius de cinta SCSI sense rebobinat L'eina per gestionar les cintes és mt Per rebobinar la cinta mt -f /dev/st0 rewind o mt -f /dev/nst0 rewind Per obtenir info de la cinta mt -f /dev/st0 status SCSI 2 tape drive: File number=0, block number=0, partition=0. Tape block size 512 bytes. Density code 0x47 (TR-5). Soft error count since last status=0 General status bits on (41010000): BOT ONLINE IM_REP_EN Note the status bits at the end of the output. These are useful, but are often cryptic. Here is an explanation of the most important ones: Status Bit Description BOT The tape is positioned at the beginning of the first file. EOT A tape operation has reached the physical End Of Tape. EOF The tape is positioned just after a filemark. WR_PROT The tape (or drive) is write-protected. For some drives this can also mean that the drive does not support writing on the current medium type. ONLINE The drive has a tape in place and ready for operation. DR_OPEN Door is open. Depending on the type of drive, this usually means that the drive does not have a tape in place. IM_REP_EN Immediate report mode. This bit is set if there are no guarantees that the data has been physically written to the tape when the write call returns. It is set to zero only when the driver does not buffer data and the drive is set not to buffer data. SM The tape is currently positioned at a setmark. DDS specific. EOD The tape is positioned at the end of recorded data. DDS specific. D_6250 D_1600 D_800 This "generic" status information reports the current density setting for 9-track 1/2 inch tape drives only. En cas de no haber-hi una cinta dins, al comprobar l'estat, veurem una cosa així: DR_OPEN IM_REP_EN Si està posat, però té la pestanya per protegir l'escriptura, veurem el següent: BOT WR_PROT ONLINE IM_REP_EN === EINA tar === Per crear un backup en una cinta usant tar tar cvf /dev/st0 / Per afegir una etiqueta tar --label="temp label" ........ == LINKS == Una web on expliquen com muntar el bacula, també diu quatre coses de com treballar amb les cintes
