raidfile-config - Configure Box Backup's RAID files
raidfile-config config-dir blocksize
dir1 [dir2 [dir3]]
raidfile-config creates a raidfile.conf file for Box Backup. This
file holds information about the directories used to store backups in. Box
Backup supports userland RAID, in a restricted RAID5 configuration, where 3
and only 3 'drives' are supported. You can read more about RAID5 (and other
RAID-levels) here[1].
The parameters are as follows:
config-dir
The directory path where configuration files are located.
Usually this is /etc/box. raidfile.conf will be written in this
directory.
blocksize
The block size used for file storage in the system, in
bytes. Using a multiple of the file system block size is a good strategy.
Depending on the size of the files you will be backing up, this multiple
varies. Of course it also depends on the native block size of your file
system.
dir1
The first directory in the built-in RAID array.
dir2
The second directory in the built-in RAID array. If you
are not using the built-in RAID functionality, this field should be ignored.
You should not use the built-in RAID if you have a hardware RAID solution or
if you're using another type of software RAID (like md on Linux).
dir3
The third directory in the built-in RAID array. The same
notes that apply to dir2 also apply to dir3.
Note that there are currently no way to add multiple disk sets to
the raidfile.conf file using command line tools, etc. See
raidfile.conf(5) for details on adding more disks.
If you find a bug in Box Backup, and you want to let us know about
it, join the mailing list[2], and send a description of the problem
there.
To report a bug, give us at least the following information:
•The version of Box Backup you are running
•The platform you are running on (hardware and
OS), for both client and server.
•If possible attach your config files
(bbstored.conf, bbackupd.conf) to the bug report.
•Also attach any log file output that helps shed
light on the problem you are seeing.
•And last but certainly not least, a description
of what you are seeing, in as much detail as possible.
raidfile-config generates the raidfile.conf(5)
file.
