Backup to .. the cloud!7 months ago
So I now have some cloudstorage space available also via webdav and I am working on using this for backups. The main idea is to have a daily backup to the cloud service and do the tape backups less often. I still want incremental backups so I can go back to specific older versions of files. So I want to use amanda for backups. I installed the davfs2 package to be able to mount the webdav filesystem and access it from Linux. The first few clues come from Set Up Virtual Tapes - Amanda Howto but I had to switch to the chg-multi driver as described in Backup to Virtual Tapes on a non-UNIX Filesystem - Amanda Howto because the webdav filesystem does not support symlinks. I/O performance during the backup isn't ideal and the vdsl uplink is completely full during the filetransfer. Maybe I need to slow down the backup process a bit and ratelimit the webdav transfer.
