Backup File is displaying negative file size on Raspberry Pi-4 #590
Description
User submitted:
I did a backup with “file list analysis”,. The filelist.log does not show any anomalies.
The file size in the backup overview is -25290772 B.
The archive.log mentions: “[2024-05-15 07:06:01 UTC] Archive filepath / size: /var/www/html/wp-content/boldgrid_backup_O8iL9XKdK2mT/boldgrid-backup-www.softpol.net-a5b7ba1e-20240515-060732.zip / -25290772 ()“
Linux sees the file as: “-rw——- 1 www-data www-data 4,0G 15 mei 09:06 boldgrid-backup-www.softpol.net-a5b7ba1e-20240515-060732.zip”
The mail, I received after completion, says “Total size: 4.33 GB”.
FYI: this website is running on a Raspberry Pi-4. The CPU is of the type aarch64, but the OS is 32-bit Debian. I am afraid that you store the file size in an “int” type variable, with PHP_INT_MAX = 2147483647, while the size of the backup is 4269676524.
About the negative file size (on Raspberry Pi-4): this bug report may be helpful. It's a bug report, where casting on an int variable returned a negative free space value.
