**Automatic Snapshot Creation**
Next to manual snapshot creation, snapshots are also created automatically.
· A cron-job creates hourly snapshots.
· Certain programs like YaST and zypper create pre/post snapshot pairs when modifying the system.
Hourly snapshots by default are disabled. So, apparently it is not snapper itself but other programs calling snapper to create the snapshots. It may be tedious to trace and (if possible) stop that.
You may rather care for the clean up and the maximum space to set up. My /etc/snapper/configs/root is as follows (I didn’t modify it):
# subvolume to snapshot
SUBVOLUME="/"
# filesystem type
FSTYPE="btrfs"
# btrfs qgroup for space aware cleanup algorithms
QGROUP="1/0"
# fraction of the filesystems space the snapshots may use
SPACE_LIMIT="0.5"
# users and groups allowed to work with config
ALLOW_USERS=""
ALLOW_GROUPS=""
# sync users and groups from ALLOW_USERS and ALLOW_GROUPS to .snapshots
# directory
SYNC_ACL="no"
# start comparing pre- and post-snapshot in background after creating
# post-snapshot
BACKGROUND_COMPARISON="yes"
# run daily number cleanup
NUMBER_CLEANUP="yes"
# limit for number cleanup
NUMBER_MIN_AGE="1800"
NUMBER_LIMIT="2-10"
NUMBER_LIMIT_IMPORTANT="4-10"
# create hourly snapshots
TIMELINE_CREATE="no"
# cleanup hourly snapshots after some time
TIMELINE_CLEANUP="yes"
# limits for timeline cleanup
TIMELINE_MIN_AGE="1800"
TIMELINE_LIMIT_HOURLY="10"
TIMELINE_LIMIT_DAILY="10"
TIMELINE_LIMIT_WEEKLY="0"
TIMELINE_LIMIT_MONTHLY="10"
TIMELINE_LIMIT_YEARLY="10"
# cleanup empty pre-post-pairs
EMPTY_PRE_POST_CLEANUP="yes"
# limits for empty pre-post-pair cleanup
EMPTY_PRE_POST_MIN_AGE="1800"
Maybe this helps you when checking “man snapper-configs”.
Based on the output above, it means that snapshots are not present due to the lack of the /.snapshots subvolume. Even though automatically enabled during install time based on conditions, it’s possible they were manually disabled during that time.
First, Gb means Gigabit which is likely not what you mean. Pay attention, we cannot read your mind.
As for wiki - minimal size of root partition to (automatically) enable snapshots is distribution (and time) dependent. For current Tumbleweed and Leap it is 25GB, but it may change in the future.
