Limitations in Syncrify
Often users ask us if there are any limits on either the file size or bandwidth usages in Syncrify. The answer to this question is no.
There are no limits on files size that are backed up or network bandwidth. However, keep in mind that Syncrify gets installed in your network. Therefore, you have to make sure you don't run out of hard disk space when backing up large files. Similarly, when you transfer large files, you have to ensure your network can support it.
Limitation in HTTP protocol regarding file size
Files are typically uploaded to the web server using HTTP POST method, which requires the content length of the file to be sent to the server prior to actual data transfer. This length is represented with an Integer. The largest value an integer can hold is about 2.14 GB. Therefore, using a regular browser you cannot upload a file greater than 2.14 GB to any web server.
This limitation does not exist when you use Syncrify client to perform the actual backup. Syncrify client intelligently handles this situation by chopping up the file in multiple chunks in a way that each chunk is smaller than the theoretical limits.
