What's the maximum file size for a file to be dumped by xfsdump?



xfsdump doesn't (really) have a maximum file size limitation. There is a maximum file size defined in xfsdump/dump/content.c but it is set to the largest theoretical file size, 18 million terabytes. The definition is defined in bytes:

/* max "unsigned long long int"
*/
#define ULONGLONG_MAX   18446744073709551615LLU

Obviously this maximum limit is impossible to hit, which is why I say xfsdump doesn't have a max file size limit. You should be able to dump the biggest possible file you can create.

There is, however, a command line option (-z) to set a maximum file size for your dump. This option allows you to specify a maximum file size, in kilobytes. Files over this size will be excluded from the dump.

When running a dump with "xfsdump -F -e -f /local/backup/weekly/sdb3.dmp -l 0 /dev/sdb3" I get the message, "xfsdump: WARNING: could not open regular file ino 4185158 mode 0x000081b0: File too large: not dumped". The file in question is 5.0 GB.
