![]() ![]() Mind Your Backup Contentsįor improving overall performance it is reasonable to exclude files of smaller importance from your backup plan (or include important files only). For big files and middle-sized files, it is recommended to use the default number of threads ( 6 in Backup for Windows, 5 in Backup for Linux and Mac) and chunk size adjusted as described in the paragraph above. For small file backups, bigger thread number and smaller chunks will be more efficient. If a network connection is not stable, smaller chunks and smaller thread count work better. Too few threads will reduce the uploading speed respectively. It is important to adjust the thread number to use network bandwidth and CPU most effectively: too many threads may create a significant load for both network and CPU and decrease overall performance. Thread NumberĬloudBerry Backup uploads data to the cloud storage in multiple parallel upload threads (in case if a storage supports multiple thread uploading) So, instead of theoretically possible bandwidth, it is reasonable to use the expected available bandwidth for upload speed estimation. Note that your host connection bandwidth is likely to be used by multiple processes on multiple machines. However, consider the recommendations of point 2.įor backup plans containing smaller files, you can use small chunks accordingly, it is recommended to use large chunks for large files. 21.5 MB cannot be split efficiently to 7 MB chunks.įor example, if the average size of a single file of your backup plan is 17 MB, you should adjust chunk size to 18 MB to optimize the process. ![]() Thus, in backup there will not be many chunks of small sizes, i.e. In fact, this is a heuristic value as chunk size (or N x chunk) must fit approximately 70% of files. The overall backup performance can be improved by adjusting chunk size with an approach as it is equal to the file size, as it is shown in the diagram below. NET Framework 4.5 cannot be installed, consider to use offline product activation Fine-Tuning Backup SettingsĬloudBerry Backup splits files into 10 MB chunks by default to upload them to storage. NET Framework 4.5 can be installed on instances running on Windows 7 or later Windows versions. See the list of allowed TCP ports (for both outgoing and incoming connections) for any firewall or antivirus. The following executable files must be in allowlist:.At first, check if Cloudberry Backup is included in the allowlist in your firewall and antivirus software: In some cases, firewalls and antivirus applications can slow down data transfers by limiting bandwidth and preventing long-time data transfers. Most Windows users (less relevant for macOS users) use firewall and antivirus software. This article guides you through backup speed slowdown issues and the measures that help to avoid them. CloudBerry Backup provides users with efficient data transmission tools but in some cases, backup processes can be slowed down. You could still configure the NAS as storage (if supported by the backup client) as well as storing the backup data on the server for redundancy.For backup duties, the data transmission speed is a key performance indicator. Having said that, depending on the number of computers you need to back up, it might be beneficial to deploy a backup server which makes managing and monitoring backups much easier. Steps 2-4 would be more or less the same if you choose to use a third party backup client. Enter credentials that has read and write permissions to the specified share.Enter a UNC path for a share on the NAS, eg.Choose to save the backup data on the network.Run Backup and Restore (Windows 7) on the computers and set up a backup job. ![]() Synology has an article explaining how to set this up using Windows 7's backup feature, which is also available on later versions of Windows. You don't mention which OS the computers are running, but I am assuming Windows. You would need to run some sort of backup client (or use Windows' own) on the computers, in which you create a backup set defining the files to back up and where to store the backup data.
