1 | .TH DOADUMP 8 "UKC local %G%" |
| 2 | .SH NAME | |
| 3 | doadump,dumpall \- perform cyclic file system dumps | |
| 4 | .SH SYNOPSIS | |
| 5 | .B /etc/doadump | |
| 6 | .I file-system | |
| 7 | .br | |
| 8 | .B /etc/dumpall | |
| 9 | .SH DESCRIPTION | |
| 10 | .I Doadump | |
| 11 | is used to perform cyclic dumps of the filesystem given as an argument. | |
| 12 | It uses the locally added tape labelling facilities of the | |
| 13 | .I dump | |
| 14 | (8) | |
| 15 | command and some data files on /etc/dumpdata which give the current | |
| 16 | dump state and a description of the cycle which is to be used. | |
| 17 | .PP | |
| 18 | The main data file is | |
| 19 | .B /etc/dumpdata/dumpcycle | |
| 20 | which contains lines of data which specify which tape set and dump level | |
| 21 | are to be used for a particular dump in the cycle. | |
| 22 | The file can contain lines starting with `#' which are comments. | |
| 23 | The columns on the file are tab separated and are: | |
| 24 | .TP "\w'Cycle number'u+3" | |
| 25 | Name | |
| 26 | the name of the device to be dumped, this is the block device name | |
| 27 | ( hp0a not rhp0a). | |
| 28 | .IP "Cycle Number" | |
| 29 | This is a number which defines the state number in the cycle to which this | |
| 30 | line refers. | |
| 31 | .IP "Next Cycle" | |
| 32 | The entry gives the next entry in the cycle. | |
| 33 | .IP "Dump level" | |
| 34 | The dump level which is to be used for the dump. | |
| 35 | .IP "Tapes" | |
| 36 | A single tape, a tape range or a list of tapes which are to be used for the | |
| 37 | dump in that state. | |
| 38 | .PP | |
| 39 | The program maintains a file called /etc/dumpdata/<device>.state | |
| 40 | which contains the | |
| 41 | cycle number of the last dump action on that file system. | |
| 42 | .PP | |
| 43 | The program | |
| 44 | .I /etc/dumpall | |
| 45 | uses the | |
| 46 | .I dump | |
| 47 | (8) | |
| 48 | program to determine which file systems require dumping and calls doadump | |
| 49 | appropriately. | |
