You need to have a device capable of file-sharing and configuring accounts and permissions.Veeam is super-easy to setup, and if you do not mind backing-up entire partition, it might be a free solution of choice for you. Veeam has neat option to store credentials for accessing remote file share, which greatly simplifies things: Here is the pic of Veeam Endpoint Backup options one can choose from: Unless you have a really small number of files. If you want to backup only specific folders and not entire drive, “File level backup” option is super-slow, and unfortunately unusable. Veeam Endpoint Backup is free and easy to configure, but only “Volume level backup” mode is usable, and that backups entire partitions. Some enterprise backup systems can do that, but they cost money. automatic (no human to forget to backup).file versioning resilient to repetitive encryption.backup location YOU CANNOT WRITE to (but backup software can).These are characterists that backup must have to protect your data from cryptovirus: Then how to be safe, how to protect your most valuable data? And from there he can change windows permissions and encrypt your files. You or anybody else (except one special account) should NOT have write permissions to a backup location. That cannot be done with windows permissions, because you are probably administrator on your computer, and therefore the cryptovirus also grabbed “administrator” privileges. You have a backup on a remote file share? If you have write permission, your backup will also be encrypted and your data are not protected from Cryptovirus. It will look for USB drives (the ones you save your backups to), and encrypt their content too, when you plug them into your PC. Third: crypto-virus will look for file shares and encrypt files it finds there. But first check if your cloud is resilient to repetitive encryption. Cloud makes sense for smal arhives, or smaller part of your archive that is additionally backed-up to cloud, or big archives that can afford to wait a week or month to restore, or restore place is also in the cloud in the same datacenter so between backup and restore location is fast LAN connection. Compare that to 1 week (or months, depending on data size and connection speed) that would take to recover from the cloud. Normal local network (LAN) speed is 1 000 Mbit/s and takes only 3h to recover 1TB of data. For example, it takes 6 days to restore 1TB of data with 20Mbit/sec internet connection. Cloud backup providers usually offer versioning, but you need to check is the number of versions limited, when repetitive encryption occurs will original file version be pushed-out after N iterations? Others cannot use cloud backup because their data is too big. You just need to remember that limited number of versions is not good enough because of repetitive encryption. more than month ago, no matter how many times the file is changed during that period. Therefore, you need versioning that will not delete the oldest version until it is really old, e.g. Second: smart crypto-viruses can flip-flop encrypt the same file repetitively more than 30 times, pushing unencrypted original version out of backup version history. to 30), after which the oldest version is deleted. But usually the number of versions is limited (eg. With versioning, if original is encrypted and copied to a backup, you could revert to a file version before encryption. To prevent that, you need a backup that supports file versioning. Storage replication will also not protect the data for the same reason – an encrypted original will be replicated to the other location too. Once originals are encrypted, next time your backup runs it overwrites your backup with encrypted files, and both your backup and original files are encrypted, unreadable. Read on.Ĭrypto-virus will encrypt your files. It might take more then a few steps to configure, but it needs to be done only once and it pays off in every way. Because we care for your data and security, we will show you how to protect yourself using free tools. You DO have a backup? Normal backup will NOT protect you from cryptovirus. They also encrypt your DB backups and all other files accessible on file shares. They cannot can encypt your SQL Server databases, but because sql data and log files are in use by sqlservr.exe process, they first STOP your sql service, then they encrypt your databases. If it asks money (a ransom) to decrypt, we call them “ransomware”.
