![]() Yes, this will keep overall RAM usage in check, but then the performance is likely going to get all moody - both because of the change in the swapping behavior and because running several backups in parallel will saturate the hell out of IO pipeline. ![]() Now let's say these limits become dynamic, because we impose a limit on their cumulative size across all active jobs. this is reasonably simple and predictable. When an item is trimmed from the object cache, its blob is pushed down to a page in a swap cache, and the page is flushed to the disk once total swap page count goes over swap.max_pages. Once cache reaches number of items, the least recently used ones are trimmed until the cache is reduced to items. ![]() These (at, to) pairs control the size of object cache for files (f), directories (d) and steps in a backup plan. To limit in-memory swap cache to half-gig and the perhaps set In your case you should just do something like It tends to sweep simpler problems under the carpet only to replace them with more contrived ones.įor every case when this sort of dynamic RAM capping will work, there will be a case when it will kick in exactly when one doesn't care about RAM usage, but just wants for a backup to complete ASAP. To be completely honest, I really don't like overly smart software. They are read only on launch and overwritten on exit. Just make sure to *exit the app* before editing any INI files. With 32 Gigs of RAM you most certainly will want to try this. Swapping version of the tree scanner is disabled and a fully in-memory version of it is used instead. Mostly due to not being ready to commit to the INI structure.Ĭ_memory_use - what happens if it is set to false? Is there a document that describes the keys both in the main config and the profile config? Then, if they run and there's remote shares are not accessible, the runs will fail. If prep_net_backups is OFF, then backups will be put into "ready" state directly. Network monitor periodically checks all shares on its list and when one becomes accessible, it pokes respective backups and they advance from "expecting a device" to "ready" state. In particular, this supplies the monitor with share access credentials (as configured in the backup settings), so it will connect shares if they aren't yet accessible. When enabled (which is the default), it adds all network locations (including mapped drives) of all enabled real-time and periodic backups to the network monitor module. This is an option used during at-launch initialization. Frankly, I don't know why we still haven't removed it from the app, we really should've. The only effect is that the "Working Set" metric in Process Explorer will go down. There is absolutely no practical reason to do that. When enabled, this feature will force bvckup2 to periodically trim its own working set (ws). Relative will work too, but bvckup2 doesn't set up current directory when it starts up. Swap.max_pages and swap.page_size shape the "bulk IO cache" layer. Thinking about wear and tear on SSD drives, I note that there are ~scanner-dst and ~scanner-src swp files written out constantly - clearly to save on ram. What happens if it is set to false? If I have a machine with 32G of spare ram can I configure bvckup 2 to use it? Is there a document that describes the keys both in the main config and the profile config? It would be super useful to access it. Then there is the alluring swap.location key which has no value.Ĭan I specify an absolute or relative path with this?Īnyway, I'm going to try to symlink the entire config folder to non SSD location. I see that the default size of these is set in the ini to be : Thinking about wear and tear on SSD drives, I note that there areįiles written out constantly - clearly to save on ram. Aug 24, 2016I'm realtime synchronizing about 3TB data comprising of up to 10 million files in around 100,000 folders.
