Description:
Compare objects with adjustable accuracy and speed
Usage:
diffuzzy [OPTION]... PATH1 PATH2 [PATH3]...
Options:
-h, --help
Output this help message and exit.
-m,--method method1,method2,...
A comma-separated list of which comparisons to run:
e,existential default Detect missing objects
u,uid Compare user ID number
g,gid Compare group ID number
m,mode Compare file mode bits
t,type default Compare file types
s,size default Compare file size
d,data default Compare header, footer, and offsets
h,header default Compare the first 512 bytes
f,footer default Compare the last 512 bytes
o,offsets default Compare a set of 512 byte offsets
b,blockdata Compare block device data
--offsets rlog2
A comma-spearated list of 512 byte offsets to compare:
rlog2 A set of floor(log(2,size)) random 512 byte offsets. Default.
log2 1,2,4,8,... up to floor(log(2,size))
log2log 1,2,4,8,...,last-1,last-2,last-4,last-8...
n Specify how many random 512 byte offests.
--unittest
Perform unit tests to verify functionality of this script.
-v
Output each set of files that are compared.
--verbose #
Use more or less verbose output. Valid values are:
0 Default. No output.
1 Show compared files.
2 Show detailed comparison information.
Examples:
Compare three different paths recursively with fast random offsets
diffuzzy /mnt/storage /mnt/backup_local /mnt/backup_offsite
Compare two paths with additinal offsets for higher accuracy
diffuzzy --offsets log2log,rlog2 /mnt/storage /mnt/backup_local
Compare only one random offset to minimize load
diffuzzy --offsets 1 /mnt/storage /mnt/backup_offsite
Verify objects exist and with matching size
diffuzzy -m e,s /mnt/storage /mnt/backup_offsite
Verify existing objects have matching size and ignore missing objects
diffuzzy -m s /mnt/storage /mnt/backup_offsite
Verify objects exist and with matching mode bits
diffuzzy -m e,m /var/public /mnt/remote-public
