Re: [BackupPC-users] BackupPC 4.x on Raspberry PI?
Just as an update... I have been running BackupPC 4.x on my RPI4 with 8GB memory and an external USB 1TB Samsung SSD. It's been ROCK STABLE for the past 7 months -- no crashes in more than 200 days and I only rebooted once due to a kernel upgrade. So in summary, it's a simple, fast, stable, small footprint, and affordable backup system. (Full disclosure, I use it as a secondary backup to my Linux BackupPC server) G.W.

In my (expert) opinion it's fundamental to the design. It's well known that the USB design was flawed when it was first brought out. It was widely publicized that the incorrect use of a single 'pull-up' resistor violated the USB spec (two resistors were required, and I believe that later versions were updated to have two resistors). The fact that a mistake like that could get into production makes me wonder what else is wrong. Although I have no hard evidence to offer, the behaviours I've seen lead me to suspect that something else in the design is at the very least marginal. Obvious candidates are power conditioning and the USB circuits but it could be something completely different and it could be more than one thing. At one time I had the idea of using the 4B in a product but I abandoned the idea. If I were going to use the 4B I'd be finding out exactly what the problems are before I'd commit to it. i.e., if I can keep the heat down, will it be stable? Not if your definition of stable is anything like mine, and your Pi4Bs behave anything like the several I've used. See my previous posts. I strongly recommend that the 4B is not used for anything as important as your backups. In my experience the 3B+ is fine. I've been using one for backups for more than a year, and one as a database and file server for quite a bit longer than that, with no issues although the database server does I admit occasionally creak a bit. It's only ever fallen over when the OOM killer killed something that I shouldn't have let it kill (rpc.mountd!) and having written the appropriate values to /proc//oom_score_adj it now trundles along quite unflappably. In any case, a 3B+ is well up to it, the extra power of the 4B won't be needed unless your backups are extraordinary. -- 73, Ged. ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/

They all do it. It isn't an overheating problem. Some of them aren't even in cases - they're mounted on flat panels (which are in turn mounted vertically for maximum convection cooling) and the rooms in which they run are very cool. Nagios says the temperatures are fine at the crash but they do throttle themselves at high temperatures anyway.

My wife uses one for desktop stuff and it's more or less fine for that use. It can be left running idle for many weeks; the best uptime ever according to Nagios was about 110 days. It crashed (around lunchtime) on New Year's Day after 68 days when (we think) she was thrashing a database. But if for example she connects a powered USB device like a second HDD it's almost bound to crash immediately. So after a few bad experiences there are things we just don't do now, and that's how we can manage to get more than a couple of days uptime. > > Mine doesn't have a load like backuppc ... I'm pretty sure that load is one of the issues. Running as a database server here, the disc is thrashing constantly, 24/365.

Wondering what model 4B the OP is using? (2Gb, 4Gb, or 8Gb?) They're all 4GB. They were purchased well before the 8GB was released.

I've had problems with very different setups - file servers, database servers, backup servers, performance monitoring, security cameras (both USB and IP) and desktop. All were the same basic OS, but different application software. All continuous, if not necessarily all heavy, system usage.

Re: [BackupPC-users] BackupPC 4.x on Raspberry PI?
Has anybody had good success running BackupPC 4.x on a Raspberry PI? Looks like a quite popular question. Standard Raspbian software comes from Debian, and the present Debian (Buster) BackupPC package is (and will remain for quite some time) BackupPC 3: you have the choice of (a) installing BackupPC 4 from from the tarball - has been done (see https://github.com/backuppc/backuppc/issues/265), but is not quite evident, or (b) trying to run some other distro on the Raspberry (most of them, except Ubuntu, have packages that use BackupPC 4). From the point of view of performance, I would be optimistic. I have had good experience porting a quite complex Gtk GUI (music catalogue application) from my PC to a Raspberry PI - amazing that, although the response times with the PI are slightly sluggish, the Raspberry turned out to be a quite acceptable alternative to the PC (I am using the 8GB RAM variant, but merely for being defensive). The main question with respect to BackupPC is efficiency of Raspberry USB. My music application uses rsync to synchronise the catalogue (200 Gbytes) between the PC and the PI - works without problem, but is not super fast. Good luck! ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/
