I would like to have my clients back-upped to two or three different locations. At first I thought to install three UrBackup servers, but it seems that we cannot have more than one internet server linked per client.
I looked around in the forum here and many people suggested backing up the actual ‘urbackup’ directory containing the whole back-up structure. I have tried this with three tools so far, Duplicati, Resilio Sync and Syncthing. All three just keep indexing the files and eventually crash while using multiple GB’s of RAM.
I assume they are crashing because of a loop in the Symlinks, or just not handling symbolic links in a correct manner. For Resilio Sync, I even found an option to disable symlinks completely. That would certainly be a pain in the ass if I ever had to do a manual restore, but it would be an acceptable solution. However, it still crashes.
Users of Urbackup: What tools do you use to sync your directory with back-ups to another server/device? And how big is your pool? My UrBackup pool is 990GB large and consists of mainly webservers and web-applications, so lots of small files.
I don’t use file backups, but only image backups, given that they provide me with the posibility of disaster recovery as well as the posibility of individual file recovery by mounting them. I sync the backup to an offsite location using rsync in Linux (CentOS), the image backups don’t seem to use symlinks so i have no issues with offsite copy. The amount of data depends a little on the urbackup server, but usually around 3-5 TB per server.
Thanks for your input! I’m using file backups right now because I didn’t care for the added complexity of imaging and to be able to restore certain files quickly. However, image backups might actually be better. And they might sync better off-site and be a little bit more manageable than the 1-million-plus directories that syncthing is currently reporting .
Uroni: am I right in reading your suggestion as follows: Install urbackup client on the first backup server, and use urbackup server on the off-site server to image the first one? That would mean I don’t even have to tinker with the client-to-server backups I’ve got running now.
