Re: Is automatic wakeonlan possible?

If the machine has a timeout, say 1 hour, then either solution will allow the estimate to be performed, but the backup itself may fail if it is more than 1 hour between the estimate and the backup. Solutions: 1. Do not allow automatic sleep on servers that need backup. 2. Let the amanda server start a script that keeps the clients wake during the backup time: write a marker-file, and start a script in the background that does wakeonlan e.g. every 15 minutes as long as the file exists. When amdump is finished, remove the file. You could even parse the output of amstatus and let the wakeonlan only bother with machines that have not done yet: amstatus config --waitdumping --estimate --gestimate would list the necessary machines (no need for --dumping, because real activity does not let the machine go to sleep). I would prefer solution number 1. -- Paul Bijnens, XplanationTel +32 16 397.511 Technologielaan 21 bus 2, B-3001 Leuven, BELGIUMFax +32 16 397.512 http://www.xplanation.com/ email: [EMAIL PROTECTED] *** * I think I've got the hang of it now: exit, ^D, ^C, ^\, ^Z, ^Q, ^^, * * F6, quit, ZZ, :q, :q!, M-Z, ^X^C, logoff, logout, close, bye, /bye, * * stop, end, F3, ~., ^]c, +++ ATH, disconnect, halt, abort, hangup, * * PF4, F20, ^X^X, :D::D, KJOB, F14-f-e, F8-e, kill -1 $$, shutdown, * * init 0, kill -9 1, Alt-F4, Ctrl-Alt-Del, AltGr-NumLock, Stop-A, ... * * ...

Re: Is automatic wakeonlan possible?
Thanks for the suggestion. A wrapper (or part of the cron job) only handles part of the problem. If the machine has a timeout, say 1 hour, then either solution will allow the estimate to be performed, but the backup itself may fail if it is more than 1 hour between the estimate and the backup.

I have a few options: I could try hard to keep the machines from going to sleep, but any user can put some of the machines to sleep. I could ignore the problem, and skip backing up machines which are asleep. I could use wakeonlan to wake up all of the machines which are subject to narcolepsy. My cron job could easily run wakeonlan for all of the machines before amdump starts. This will usually make the estimates run correctly. The dump itself may fail if the machines automatically sleep. Both dump and estimate are subject to failure if people put the machine to sleep, but this is probably less of a worry.

Re: Is automatic wakeonlan possible?
Oops. I misread the position of the wrapper. Since the wrapper described on http://www.amanda.org/docs/howto-wrapper.html runs on the client, the wrapper won't work if the client is asleep.

I don't backup desktops/workstations. There's a central fileserver available for things that people want/need to backup on their workstation/desktop.
