The following ones are much faster, but it depends on how much you change. Only the changes are saved. rsync Follow our rsync tutorial first. The snapshots are stored locally and remotely via rsync daemon. This backup solution is only recommended for an internal network. Use an encrypted backup method with borg instead. Dependencies The script needs inetutils for hostname command. pacman -S inetutils Credentials echo "$password" > /etc/rsyncd.password chmod 400 /etc/rsyncd.password Script Add your details for DAEMONUSER=“” and DAEMONHOST=“”. nano /root/rsnapbackup.sh #!/bin/sh ## Based on: ## my own rsync-based snapshot-style backup procedure ## (cc) marcio rps AT gmail.com # config vars SRC="/" SNAP="/root/backup/" OPTS="--rltogiPhv --stats --delay-updates --delete --chmod=a-w" EXCL="--exclude-from=/root/backup-filter.rule" DAEMONUSER="" DAEMONHOST="" HOSTNAME=$(hostname) MINCHANGES=1 # run this process with real low priority ionice -c 3 -p $$ renice +12 -p $$ # List and save installed packages pacman -Qn | awk '{ print $1 }' > /root/pkglist # sync rsync $OPTS $EXCL $SRC $SNAP/latest >> $SNAP/rsync.log # check if enough has changed and if so # make a hardlinked copy named as the date COUNT=$( wc -l $SNAP/rsync.log|cut -d" " -f1 ) if [ $COUNT -gt $MINCHANGES ] ; then DATETAG=$(date +%Y-%m-%d-%H:%M) if [ ! -e $SNAP/$DATETAG ] ; then cp -al $SNAP/latest $SNAP/$DATETAG chmod u+w $SNAP/$DATETAG mv $SNAP/rsync.log $SNAP/$DATETAG chmod u-w $SNAP/$DATETAG fi fi rsync -avAXHP --delete --password-file=/etc/rsyncd.password $SNAP rsync://$DAEMONUSER@$DAEMONHOST/archive/backup/$HOSTNAME chmod +x /root/rsnapbackup.sh Exclude folder and files This is an example.

Add device Add the backup server to your client under Remote Devices. Add folder Add a folder under Folder and select the folder you want to backup under General. Select your backup server under Sharing. Under File Versioning you could add Staggered File Versioning which gives you more certainty, but have a look at https://docs.syncthing.net/users/versioning.html and choose what suits you best. Also check Advanced and Folder type and again choose what suits you best. For example, Keepass can be used with Send & Receive if you want sync your database on both devices. 2022/02/25 21:13 · dan en/backup/desktop.txt Last modified: 2022/02/25 21:14by dan
