Excluding files from regular R1Soft backups can save bandwidth and storage space. But it also costs time. In fact, excluding very large numbers of files can add days to the time it takes to back up your server – unless you follow this guide to excluding files efficiently in R1Soft.
Why does file exclusion take time?
R1Soft server backup manager is block-based backup. And while block-based storage is very flexible and convenient for storing and accessing data, it is at odds with excluding certain files and including others.
In order to exclude files, the R1Soft system reads all the blocks of data on your server in order to find the files to be excluded, then excludes them as blocks. Even excluding whole folders requires this process to be run in order to exclude all the correct files.
This means that file exclusion is a very useful feature if you wish to exclude one or two files. But when you wish to exclude whole folders and large numbers of files, the process becomes very inefficient and the time it takes to run a backup may become impractically long.
How can you reduce the time it takes to exclude files?
In order to get around this problem, create a disk partition for the folders that you wish to exclude. This is far more convenient for the block-based R1Soft system to deal with, as the entire partition can be excluded from your backups.
Although creating a partition may seem like a big step just for managing your backups, if you’re reading this it’s probably because you have large quantities of data on your server that do not need to be backed up, but would cost a lot of money or resources in terms of disk space and bandwidth, in which case properly configuring your server for backup would be worthwhile.
