helps__1=`TN_ "The identifier for the server. Default: The official hostname, followed by a colon and the full path to the configuration file. The server identifier can be used to become independent of the server machine name. This might be helpful, if the backup server should move to another machine. Whitespace characters may be used in this identifier, but they are replaced with asterisks * before comparing, so they are not significant."`
helps__2=`TN_ "This is the device, the backup is written to. It can be any tape device with the capability to distinguish several files on the media. It is mandatory to supply the no-rewind device here. Otherwise this package won't work properly. This may also be the path of a directory. Then the backup is written to files in this directory. Suitable device names for some OS-es:\nAIX:          /dev/rmt0.1\nSolaris:      /dev/rmt/0bn\nIRIX:         /dev/rmt/tps0d4nr\nHP-UX:        /dev/rmt/0hn\nLinux:        /dev/nst0\nDigital UNIX: /dev/nrmt0h\nFreeBSD:      /dev/nsa0\nIf the drive has a media handler attached, a specifier for this may follow the device name. The format for this is =<drive-count>@<device>#<num-slots>^<num-loadbays>, for example =1@/dev/sg0#6^2 . Whitespace before and following the special characters = @ and # is allowed for readability. The example means: The drive is number 1 in the changer, /dev/sg0 is the changer device, that has 6 media slots and 2 loadbays. The parts =<drive-count> and ^<num-loadbays> are optional.\nIf the server is only used for remote start and no real backup device should be accessed, a dash - should be configured here as device, so a respective warning to the server log will be suppressed."`
helps__3=`TN_ "The blocksize of the tape device. This value specifies, how many bytes are written to tape or read from it in one system call. Usually this value is at least 512 or a multiple of it. It is not very important, whether the blocksize is set to 2048 or 1024. The main thing to keep in mind is that if there is a minimum, it should be respected (e.g. 1024 on AIX), otherwise media space is wasted."`
helps__4=`TN_ "Three numbers and a filename can be given here. The first number is the desired size of the tape buffer in bytes. The optional second number is the high-watermark while writing in percent (default: 67), the optional third number is the low watermark, also in percent (default: 0). As long as the buffer fill rate does not reach the high watermark, nothing is written, but when it is reached, writing does not stop until the buffer fill rate is equal or below the low watermark. This procedure hopefully reduces tape wear and increases average writing speed, because excessive tape stops/starts are avoided. If the optional filename is given, buffering is done in the given file, which is mapped into the server's address space for that purpose. In the filename, patterns are replaced like with Changer-Configuration-File (18)."`
helps__5=`TN_ "This value must be 1 or 0, what means, that you either have a cartridge handling system (i.e. some kind of robot) (1) or not (0). If you don't have a robot, you may nonetheless maintain a set of cartridges, that you have to number manually. The backup server side will inform you via email or console output, whenever another cartridge has to be inserted into the drive and what number it requires it is."`
helps__6=`TN_ "This number specifies, how many cartridges you are maintaining. If you have a cartridge handling system (some kind of robot), this is usually the number of cartridges, your system is juggling."`
helps__7=`TN_ "Several cartridge sets can be used. Here they can be specified. The specifiers for the cartridge sets must be separated by whitespace. Each specifier may consist of digits, commas and dashes. Examples for cartridge set specifiers: 1-5 7-9,12 6,10,11 This example shows how to specify three cartridge sets. If this parameter is not given, there is only the default set number 1 containing all available cartridges. Not all cartridges need to be included in a set and sets must not overlap. See the man-page of afserver.conf how to configure client access restrictions for cartridge sets individually."`
helps__8=`TN_ "The stream of data, that represents your backup, is divided into pieces (files on tape). This is done to find the files faster during a restore. This value determines, how large the pieces on tape may be in bytes. Some good values for a few tape technologies:\n  DAT:              30000000\n  Exabyte:          50000000\n  DLT:             100000000"`
helps__9=`TN_ "With this entry the number of bytes written to a single tape can be limited. Serveral entries with a leading range specifier allow to handle certain tapes differently. The range specifier must end in a colon : and may contain lists of ranges and numbers. A given number without a leading range specifier will be valid for all tapes not explicitly described. Default is use of full tape capacity. Several entries must be separated by whitespace and may look like the following examples: 4000000000 1,3-5:3500000000 7,9-:5000000000"`
helps__10=`TN_ "Normally, when the insert (writing) position is forced to another tape with the cartis command or with the clientside option -G, the rest of the current tape remains unused. When this option is set to 1, it will nonetheless be used to write data on, if there is no free tape left."`
helps__11=`TN_ "In default mode, the place (tape and tapefile), where the next data will be written, is fix and can only manipulated using the command cartis or the clientside option -G. When the server wants to write with variable append mode enabled, any cartridge, that is in the drive, is belonging to the right cartridge set and is allowed to be written, will be accepted and appended to. Note, that this will also override the settings of cartis or option -G."`
helps__12=`TN_ "Default is to accept an unlabeled tape as the requested one and to label it automatically. If this behaviour is unwanted and only tapes with a recognized label should be permitted for writing, this parameter should be set."`
helps__13=`TN_ "When a tape gets full and another one must be chosen to continue writing, the server does not make a difference, whether a tape is available in a changer or not, if this flag is not set. This is the default. If this parameter is set, the next cartridge is chosen from those, that are available in the slots of a changer, if present and configured. If there is no tape found inside the changer, that is allowed to be overwritten, manual administrator interaction is nonetheless required."`
helps__14=`TN_ "This is the time in seconds, the program waits after another cartridge has been put into the drive. Normal devices need a certain time span to mount the tape to get it ready for use. Normally this value is not critical. If you estimate it too low, the ioctl-system-call will wait until the device becomes available. This time is sometimes longer than two minutes, so if you want to proceed quickly after a cartridge change, you may measure the maximum time, your system needs. Some tried values for a few tape technologies:\n  DAT:         30\n  Exabyte:     70\n  DLT:         70"`
helps__15=`TN_ "If the streaming device is not accessible (i.e. an open or a tape handling command fails) or another backup server process is still running, the server process re-tries his attempts regularly. If it fails longer than the time in minutes supplied here, an e-mail is sent to the configured user in charge (see: User To Inform). Supplying 0 means: never send mail."`
helps__16=`TN_ "If the streaming device is not accessible (i.e. an open or a tape handling command fails), the server process re-tries his attempts regularly. If it fails longer than the time in minutes supplied here, it exits silently leaving a warning in the log file. Supplying 0 means: try forever, never exit."`
helps__17=`TN_ "This is the interval in seconds, after that regularly the device is probed to be ready for reading. Thus after having ejected a cartridge it is automatically recognized, if a new cartridge has been inserted. For other media (e.g. exchangeable disks) this may not be suitable. Supply a 0 in these cases for no probing."`
helps__18=`TN_ "If a media changer is available and it should be used, this is the file to configure it. It must contain specifications of the commands, that are driving the media changer. %L will be replaced with the full path of the lib-directory of the server, %B with the bin-directory, %C with the configuration directory and %V with the var-directory. See the manual pages of cart_ctl, how to setup the media changer operation."`

If the command you are supplying here starts to count with 1 for the first file on tape, you should insert %n for the <number>. If it starts with 0, replace <number> with %m. If you don't want to type the devicename again here, you may write %d instead. For more pattern replacements see Changer-Configuration-File (18)."`

You have to supply this either if you have no cartridge handling system (robot) or if you have no command to set the cartridge directly by number. In the latter case this package tries to maintain the number of the current cartridge in a file and to (hopefully) keep it consistent with the reality. In this case the cartridge handling system must be configured to sequential mode (automatically putting the next cartridge in, when the current one is ejected). The pattern %c, if used in this command, will be replaced with number of the current cartridge, %n with the number of the next one, that is expected to be put into the streamer by a robot in sequential mode after eject. %b can be used instead of %c if counting of cartridges starts with 0 and not with 1. The same applies for %m, what means %n minus 1. %d is replaced with the device name. %N is replaced with the configured total number of cartridges.
