    Snapshot backups spuriously max guest disk activity, causing application crashes

    Is the ability to backup locally then move to a PBS anywhere on the roadmap? The backup latency for offsite backups is a bit crippling, though I could likely speak to my provider about getting another local HDD to use for on-site backups then replicate that datastore to an offsite backups.

    Snapshot backups spuriously max guest disk activity, causing application crashes

    Did even more reading, and came across this Is there a way to VZDump a snapshot to local storage then have it auto-move (not copy, move) to a PBS node? I would much rather have all my backups consolidated on there and have a proper system as opposed to scripts which could break at any moment.

    Snapshot backups spuriously max guest disk activity, causing application crashes

    After doing even more research, apparently vzdump used to have a --size parameter This would allow me to make the blocks smaller so writes wouldn't have to be queued up instead of having them have entire 1GB blocks. Is there any reason this was removed, and is there a way this can be bought...

    Snapshot backups spuriously max guest disk activity, causing application crashes

    I tried each cache mode individually, both with guest agent enabled and disabled, and the problems were still the same The confusing part is every 1 in 10 backups, it wont lock the entire guest IO up, and it will just run, not to mention it running flawlessly for 2 weeks before this. Stuff...

    Snapshot backups spuriously max guest disk activity, causing application crashes

    Is there a way I can just hold these reads/writes in RAM while it waits for that block to be done? The host has 128GB of RAM so should be able to handle a few megabytes for a bit, even if its a consistency risk. Failing that, is there any other remedy for this?

    Snapshot backups spuriously max guest disk activity, causing application crashes

    Image to better convey whats going on, made on a fresh test VM, with the guest agent enabled. EDIT: After removing the bandwidth limit I had added as part of testing, the VM now has large random usage spikes It will still lock up from time to time, but its less bad. I still want to know...

    Snapshot backups spuriously max guest disk activity, causing application crashes

    Hello I am experiencing a weird issue where whenever a backup job starts for a guest VM, there is a chance for the guest to report 100% disk activity and refuse to do any more writes, which causes application crashes and other issues. I cant seem to find a rhyme or reason for this to happen, as...
