Define "UNIX-friendly". Which UNIX? Furthermore, what's your architecture and system? What kind of disks do you want to use?
A good stopgap a USB or ethernet drive would be, as any backup is better than no backup. However Windows has no respect for UNIX permissions so just blindly copying files could result in much hair-pull later. You could use the udpcast utility and do something like this:
..to just keep one giant tar which should preserve the permissions of the files inside it. To restore,
Of course, make sure the drive is formatted with NTFS or something which allows Windows to create >4GB files. FAT won't do.
And if you can have the UNIX system use the drive directly? All the better.
You might have troubles reusing the disk in a RAID once you want to make one, since you'd quite likely need to blank the contents before you make it part of an array.
If you want reliable hardware, I would suggest avoiding consumer-grade stuff. Especially avoid jmicron chipsets. 3ware works pretty closely with UNIX vendors.

Is there a command used to determine whether or not a machine has been RAIDed besides using 'df -k'. I am interested b/c I am writing a script where I would like to receive some sort of notification as to whether or not a machine has been RAIDed. The simpler the info returned back, the better. ...

I was wanting to know if anyone knew how to setup RAID 0 on an old HP Unix server. It's for where I work and my boss has two hard drives and wants the second to take over if the first one fails hence RAID 0. If anyone could help me it would be greatly appreciated. (5 Replies)
Hello,

udp-receiver
UDP-RECEIVER(1) Udpcast UDP-RECEIVER(1)NAME
udp-receiver - receive files broadcast by udp-sender
SYNOPSIS
./udp-receiver [--file file] [--pipe pipe] [--portbase portbase] [--interface net-interface] [--log file] [--ttl time-to-live]
[--mcast-rdv-address mcast-rdv-address] [--nokbd] [--exitWait milliseconds] [--stat-period n] [--print-uncompressed-position flag]
DESCRIPTION
"Udp-receiver" is used to receive files sent by "udp-sender" (for instance a disk image).
OPTIONS
Basic options
--file file
Writes received data to file. If this parameter is not supplied, received data is written to stdout instead.
--pipe command
Sends data through pipe after receiving it. This is useful for decompressing the data, or for filling in unused filesystem blocks that
may have been stripped out by udp-sender. The command gets a direct handle on the output file or device, and thus may seek inside it,
if needed. "Udpcast" itself also keeps a handle on the file, which is used for an informational progress display. The command's stdin
is a pipe from udp-receiver. Example: "udp-receiver -p "gzip -dc""
--log file
Logs some stuff into file.
--nosync
Do not open target in synchronous mode. This is the default when writing to a file or a pipe.
--sync
Write to target in synchronous mode. This is the default when writing to a device (character or block)
--nokbd
Do not read start signal from keyboard, and do not display any message telling the user to press any key to start.
--start-timeout sec
receiver aborts at start if it doesn't see a sender within this many seconds. Furthermore, the sender needs to start transmission of
data within this delay. Once transmission is started, the timeout no longer applies.
Networking options
--portbase portbase
Default ports to use for udpcast. Two ports are used: portbase and portbase+1 . Thus, Portbase must be even. Default is 9000. The same
portbase must be specified for both "udp-sender" and "udp-receiver".
--interface interface
Network interface used to send out the data. Default is "eth0"
--ttl ttl
Time to live for connection request packet (by default connection request is broadcast to the LAN's broadcast address. If ttl is set,
the connection request is multicast instead to 224.0.0.1 with the given ttl, which should enable udpcast to work between LANs. Not
tested though.
--mcast-rdv-address address
Uses a non-standard multicast address for the control connection (which is used by the sender and receivers to "find" each other). This
is not the address that is used to transfer the data. By default "mcast-rdv-address" is the Ethernet broadcast address if "ttl" is 1,
and 224.0.0.1 otherwise. This setting should not be used except in very special situations, such as when 224.0.0.1 cannot be used for
policy reasons.
--exit-wait milliseconds
When transmission is over, receiver will wait for this time after receiving the final REQACK. This is done in order to guard against
loss of the final ACK. Is 500 milliseconds by default.
--ignore-lost-data
Do not stop reception when data loss is detected, but instead fill with random data. This is useful for multimedia transmission where
100% integrity is not need.
Statistics options
--stat-period seconds
Every so much milliseconds, print some statistics to stderr: how much bytes received so far log, position in uncompressed file (if
applicable), overall bitrate... By default, this is printed every half second.
--print-uncompressed-position flag
By default, udp-receiver only prints the position in uncompressed file if the 2 following conditions are met:
o Output is piped via a compressor ("-p " option).
o The final output is seekable (file or device)
With the "--print-uncompressed-position", options, you can change this behavior:
o If flag is 0, uncompressed position will never be printed, even if above conditions are met
o If flag is 1, uncompressed position will always be printed, even if above conditions are not met
