Hi Ian,
The drives are all formatted ext4. That shouldn't be the issue. In my
mind, the OS upgrade and the hard drive to SSD change are the only two
things that would seem a likely source. Did rsync change? Does the SSD
store things differently causing rsync's file comparison to flag
seemingly identical files as different?

What format is your backup drive?
If the backup drive is formatted to a file system that does not
support links (like exFAT ) hard links will be copied as duplicate
lfiles and soft links may not be copied at all.
SSDs and hard drives are usually supplied with a Windows file format,
such as exFAT or NTFS and would need to be reformatted to a linux file
system (such as the default format for your own linux systems, begore
they will work properly with rsync.

Hi all,
I have been using rsync to perform automated backups to a separate
physical drive for years. I recently upgraded my hardware, including
switching to an SSD for my main drive and upgrading my backup drive.
The other recent change, is Mint Linux 16.04 to 20.04.
My crontab executed script has not been altered.
It now appears that the backups are no longer sharing hard links, making
them use much more space. I have now filled 4TBs with backups in weeks,
when it would typically take a year to fill 1TB prior to my upgrades.
I am unsure where to look to figure out what may have changed. Any
suggestions you may have are appreciated.
My sctript ...
NOW=$(date +"%Y%m%d-%H%M")
BASE="/mnt/backup-int"
PREVIOUS=$(ls -r $BASE | head -1)
echo .
echo Starting snapshot to internal media at $NOW
echo .
if [ "$NOW" != "$PREVIOUS" ];
then
TARGET="$BASE/$NOW"
LINK="$BASE/$PREVIOUS"
OPTIONS="--dry-run -rptgovDH --delete --link-dest=$LINK"
rsync $OPTIONS --include-from
'/home/carolyn/backupScripts/include-list.txt' --exclude-from
'/home/carolyn/backupScripts/exclude-list.txt' $SOURCE $TARGET
fi
...
Thanks for your assistance!
