[opensuse] cron and storebackup setup
Hi Everyone, It has been some time since I have been watching the list - my life got really busy over the past year and only now I think I will be coming back to read the emails more frequently. I have a little problem I hope someone can help with. I run storebackup dailyon my 13.2 box that I just got back up and running, having it set up to run in /etc/cron.daily, along with the other programs that are in there. The problem is, storebackup ends up taking a lot of resources while it is doing the backup, and can slow down the pc enough to be kind of annoying. So I would like to run it in the middle of the night. Unfortunately, electricity is really expensive here, and I don't want to run my computer all night long or I will build up a pretty big energy bill. So I was thinking, maybe I can add the line pm-suspend to the script that runs storebackup, and then set the cron.daily time to go at 1 am, or something like that. The idea being, I will leave my computer on when I goto bed, then in the middle of the night it will run the storebackup job, and when it is done, it will suspend to ram and save my energy bill. But then I am thinking, what if it finishes running storebackup before running the other cron jobs, then goes to suspend, and they don't get run? Will there be a problem if thesystem is put in suspend to ram mode while another cron job is in the middle of running? Is it possible to somehow set things up to have the storebackup cron job be the last one to run,and only after all the others have run? -- George Box #1: 13.2 | KDE 4.14 | AMD Phenom IIX4 | 64 | 16GB Box #2: 13.1 | KDE 4.12 | AMD Athlon X3 | 64 | 4GB Laptop #1: 13.1 | KDE 4.12 | Core i7-2620M | 64 | 8GB Laptop #2: 13.2 | KDE 4.14 | Core i7-4710HQ | 64 | 16GB -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

which resources? RAM, CPU, disc, network, ...? I don't know storebackup, but did you try 'nice' and 'ionice'? Have a nice day, Berny -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Have a nice day, Berny storebackup uses bzip2 to backup everything, and the algorithm is able to compress and save quite a bit of disk space, and it makes it easy to restore. I keep 30 days worth of backups on a separate drive, in addition to my RAID1 drives to protect from drive failure, and that seems to be a helpful way of doing things for me.
bzip2 seems to use a lot of processor power, not too much memory. The
system load viewer right now, as I am running it, shows 5 different
bzip2 processes running simultaneously, all of which are taking up about
14% of the CPU.
This is the script that calls storebackup in the cron file, if anyone is
interested:
----------------
#! /bin/sh -e
# run storeBackup on all files in /etc/storebackup.d/ sequentially
# file names must consist entirely of letters, digits, underscores, and
hyphens

maybe there's a configuration file which would limit the number of simulataneous bzip2 processes to e.g. 2. Anyway, I'd try using an even more relaxing 'nice' value (see 'man nice'):
if ! nice storeBackup -f "$file" > "$tmplog" 2>&1
... nice -n19 storeBackup By that, all regular processes should get more percentage of the CPUs, and you shouldn't see much delay on the desktop. Have a nice day, Berny -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Only 14% each? That's /too/ little. :-) Total 60%. Not 100%. Or rahter, 400%, which would be full power. Your issue is probably disk speed.

It is on another drive in the computer. My external backup is done once a week - this is just for keeping incremental files backed up in case I mess something up and need to go back to a version from a month or so ago. But the drive it is on is a RAID1 drive, about a 900G ext4 format. -- George Box #1: 13.2 | KDE 4.14 | AMD Phenom IIX4 | 64 | 16GB Box #2: 13.1 | KDE 4.12 | AMD Athlon X3 | 64 | 4GB Laptop #1: 13.1 | KDE 4.12 | Core i7-2620M | 64 | 8GB Laptop #2: 13.2 | KDE 4.14 | Core i7-4710HQ | 64 | 16GB -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I would test the write speed of this. Write a big file full of zeroes with dd. Something like: dd if=/dev/zero of=file bs=1M count=100 - -- Cheers / Saludos, Carlos E. R.

To have "storebackup" cronjob run as last job, add a prefix like "zzz_" to the name of the scriptname in the /etc/cron.daily directory. And for suspend, please, do yourself a favor and use "systemctl suspend" instead of calling "pm-suspend". Also, how about creating a script / starter / .desktop-file that contains: [code] xdg-su -u root -c "/etc/cron.daily/zzz_storebackup" [/code] as command line, add this to your desktop / menu and call it before going to bed / leaving the comp to the night. That way there would be no extra wait to run storebackup, and by including "systemctl suspend" as the last command, it would do a suspend to ram after finishing.

That is an excellent idea! Thank you for thinking of that - I will take it out of the cron daily and just run it from the desktop, running it from another directory. Thank you also for pointing out the appropriate systemd command for suspend.

I use rsync to back my data up. i have it configured in a script that runs at logout or shutdown. Could you not run your script at logout as well? I also keep meaning to look for a way to run the back up script when the screensaver is running -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I normally don't log out unless I have an update that requires a reboot, or I need to reset something in KDE. But it is worth thinking about if I change my strategy.
