Backup larger than VM size

[Miro_I]

Hello,
Since the upgrade to Proxmox VE 6.4-14 i have an issue with some snapshot backups.

In VM # df -h shows 182G and backup is 301GB.
The VM has Discard enabled on the hard disk and fstrim -av inside VM was executed before backup.
Why it is creating larger backups than actual vm content size?

In VM # df -h shows 182G and backup is 301GB.

df shows disk-free ;-)

Any chance your disk is ~ 500 GByte in size?

Best regards

df shows mount point, total, used and available. I meant 182GB used. Total is 1TB
