OCI file storage snapshots are not managed automatically by OCI like block volumes backups are when using policy-managed backups.
Which means that you have to create and delete the snapshots by yourself.
On this blog post I will share a shell script to accomplish this task using oci cli.
Here is an example to create daily snapshots: fssnap.sh
# !/bin/bash export CLI=/home/oracle/ocicli export FSSOCID=<file storage ocid> export TSTAMP=`date +%Y%m%d` export ENV=prod # create snap $CLI/oci fs snapshot create --file-system-id=$FSSOCID --name=$ENV.$TSTAMP
You can get the file storage ocid at OCI console:

Create a user and group and assign the below policy to the group:
Allow group StorageAdmins to manage file-family in compartment PROD
Schedule this shell script to run on a regular internal that fits your needs.
But in my case I had to keep a limited amount of backups based on same information such as: environment (prod or dev) and customer retention policy (bronze, silver or gold).
So I wrote another simple shell to accomplish this: fscleanup.sh
!/bin/bash export CI=/home/oracle/ocicli export FSSOCID=<file storage ocid> export TSTAMP=`date +%Y%m%d` export KEEP=42 # dump backups to tempfile $CI/oci fs snapshot list --file-system-id=$FSSOCID | grep '"id"' | awk '{print $2}' | sed 's/"//g' | sed 's/,//g' > /tmp/fss.bkp #count CT=`cat /tmp/fss.bkp | wc -l` #remove backups older then $KEEP if [ "$CT" -gt $KEEP ]; then DIFF=$(expr $CT - $KEEP) for id in `tail -$DIFF /tmp/fss.bkp` do $CI/oci fs snapshot delete --force --snapshot-id $id done else echo "less then KEEP: $KEEP" fi
Please check OCI doc about managing snapshots for more info.
Let’s wait for the OCI native and automated way for doing this but until then this is the workaround.
