Statistical Output of storeBackup.pl

After creating a new backup and possibly deleting old ones, storeBackup will write some statistical output:

directories

Number of directories storeBackup found in the data source and created in the backup.

files

Number of files (more exactly: the number of links) storeBackup found in the data source. This includes all types of files storeBackup is able (or configured) to process.

symbolic links

Number of symbolic links storeBackup found in the data source.

name pipes

Number of named pipes storeBackup found in the data source.

new internal linked files

Number of files with the same contents storeBackup found in the actual backup (not in an old one). This is checked first.

old linked files

Number of files which exists in the previous backup with the same name, same size, same ctime and same mtime.

unchanged files

Number of files with the same contents storeBackup found in the old backup(s).

copied files

Files with new contents, copied to the backup directory.

compressed files

Files with a new contents, compressed into the backup directory.

excluded files because pattern

Files excluded because of option 'exceptPattern'.

included files because pattern

Files included because of option 'includePattern'.

max size of copy queue

Maximum size of copy queue during the backup.

max size of compress queue

Maximum size of compress queue during the backup.

calculated md5 sums

Number of files for which an md5 sum was calculated.

forks total

Total number of forks (number of forks md5 + forks compress + forks copy + forks named pipes).

forks md5

Number of forks for program md5sum.

forks copy

Number of forks for program cp.

forks <compress>

Number of forks for program <compress>

sum of source

Size in bytes of all files in the source directory.

sum of target all

Size in bytes of all files in the target directory.

sum of target new

Size in bytes of new copied or compressed files in the target directory.

sum of md5ed files

Size in bytes of all files for which an md5 sum was processed.

sum internal linked (copy)

Size of bytes of all files which were internal linked (see: new internal linked files). These files were linked to files which were copied into the backup.

sum internal linked (compr)

Size in bytes of all files which were internal linked (see: new internal linked files). These files were linked to files which were stored compressed into the backup.

sum old linked (copy)

Size in bytes of all files which were linked to older backups (see: old linked files). These files were linked to files which were copied into the backup.

sum old linked (compr)

Size in bytes of all files which were linked to older backups (see: old linked files). These files were linked to files which were stored compressed into the backup.

sum unchanged (copy)

Size in bytes of all files which existed with the same name, mtime and atime in the previous backup. These files were linked to files which were copied into the old backup.

sum unchanged (compr)

Size in bytes of all files which existed with the same name, mtime and atime in the previous backup. These files were linked to files which were stored compressed into the old backup.

sum new (copy)

Size in bytes of all files which were copied into the backup.

sum new (compr)

Size in bytes of all files which were stored compressed into the backup.

sum new (compr), orig size

Size in bytes in the source directory of the above files.

sum new / orig

Percentage of new files in the backup to their original size in the source directory.

size of md5CheckSum file

Size of the file <backupDir>/.md5CheckSums[.bz2].

size of temporary db files

Size of the db files generated during the backup in tmpdir.

deleted old backups

Number of old backups which were deleted.

deleted directories

Number of directories deleted in old backups.

deleted files

Number of files truly deleted in old backups (last link removed).

(only) removed links

Number of links removed in old backups (files not deleted).

freed space in old directories

Freed space in old directories, does not include meta information.

add. used space in files

Additionally used space for this backup: difference between new allocated space and freed space in old backups.

backup duration

Backup duration: time for precommand, backup, postcommand and deletion of old backups.

over all files/sec (real time)

Number of files divided by real time.

over all files/sec (CPU time)

Number of files divided by (user and system time).

CPU usage

Average cpu time for the time period of "backup duration".

PROGRESS 2009.05.09 10:16:43 22774 5000 files processed (324M, 152M) (340234099, 159903981)

 
storeBackup read 5000 files so far. The first number (324M or 340234099 bytes) is the total size of new files found on the source. The second number (152M or 159903981 bytes) is the space consumed in the backup destination by those new files. This size represents the files actually copied, the effects of compression to reduce the size, and the effects of linking to identical files already in the backup (so that additional spaced used is essentially near 0).
