Backuptask crashed when uploading to OVH Object Storage
-
I seem to be having the same issue (more or less) as Backuptask crashed thread.

upload for the Box backup part with all the emails and such. I've tried it twice now repeatedly but both times it failed the same way at nearly the same place (the second attempt was less though judging by the size as it made it to around 9000M instead of 11253 MB.
Here's the configuration of my backup set (this is a new setup, trying to upload to this Object Storage backend so I can try migrating to a new OVH instance from my current VPS provider (LunaNode)):
Note that I've tried a bunch of different configurations in memory limit, upload part size, concurrency levels for various items, and even rsync and tgz format. Issue seems to occur no matter what method is used.
Thoughts?

Usually, this means the process ran out of memory. Can you try reducing the concurrency to say 100 and also reduce part size to say 100M ? Because it's going to upload 100 files in parallel and each of 100M, that's almost 10GB memory worst case with these numbers. So, you can even reduce it further to be 80 files in parallel with 50M part size (usually individual files are way less than 50M so part size can be quite small in rsync mode)
-
@girish sure I’ll try that then. I have tried a few different configurations with those numbers, one of them was just the defaults which still didn’t work at the time. I’ll try with your latest suggestion though and see if that helps. Thanks for the quick response.

Just curious… the GUI says “up to 3 parts are uploaded in parallel” for part size… but seems like you’re saying it’s actually whatever the value of upload concurrency is, right? Have I misunderstood… where does the “up to 3” come into play for part size?

@nebulon Ah okay, I think I understand. Does that mean then that we don't really need enough memory for 3x<part size>, so much as 3x(<upload_part_size>x<upload_concurrency>) for rsync setups, right, or did I totally misunderstand?
I guess what's throwing me off a bit is the UI saying "Up to 3 parts are uploaded in parallel and requires as much memory", but that's not entirely true then is it, is it fair to say that it's more important to have enough memory for 3x(<upload_part_size>x<upload_concurrency>), given what I think I understood from Girish earlier on the upload concurrency and upload part size?
In other words, if I had part size set to 512 MB and upload concurrency set to 10, then this means I need memory of 5120 MB at the very least, right, and that's then multiplied by three or is it only the 512 MB multiplied by upload concurrency and nothing about "3"? Sorry, I think I just need the math laid out a bit to better understand this so I am not pushing the server past what it has in order to avoid the backup task running out of memory.

If a file is big (i.e > than the upload part size), we still need 3x<part size> for rsync. So, let's say you have a 5GB file, then we still need 3GB RAM (since upload part size in your screenshot is 1GB). Plus in addition, we need to memory for uploading 200 files in parallel as well. And if those 200 files contain more 5GB files, then you need add it all up. It gets complicated very quickly!
