Renaming multipart backup files

[Erol-2022]

Hello,

Let's assume that we are employing a batch file to make multipart backups :

zpaqfranz backup C:\backuparchive.zpaq C:\Source

After a certain time, consolidating the multipart archive :

C:\>zpaqfranz.exe consolidate C:\backuparchive.zpaq -to Consolidated.zpaq -space

The old and new backup files could look like the following :

backuparchive_00000000_backup.index
backuparchive_00000000_backup.txt
backuparchive_00000001.zpaq
backuparchive_00000002.zpaq
Consolidated_00000000_backup.index
Consolidated_00000000_backup.txt
Consolidated_00000001.zpaq

Deleting the old backuparchive file set is eeasy : del backuparchive.

Is it possible to add an option to zpaqfranaz to rename the "Consolidated" files to the original "backuparchive" ?

I guess renaming manually the "Consolidated" files is not enough as there are references to the current symbol "Consolidated"

The purpose is to keep intact the original batch file above to maintain a continuous backup process.

It's difficult to do because you might keep the files in the same folder. If they were in different folders, they could have the same name. You just need to change the file name inside the .txt file.

For example backup due

$zpaqfranz backupfile|2|2024-11-28 21:09:54|MD5|z:/due_00000001.zpaq
6245b6b314aeb873e37d617ff7c6f9d8 |[        1.595.891.806] <39A03CCA0D7D8796> $2024-11-28 21:09:54$ z:/due_00000001.zpaq

To tre should become

$zpaqfranz backupfile|2|2024-11-28 21:09:54|MD5|z:/tre_00000001.zpaq
6245b6b314aeb873e37d617ff7c6f9d8 |[        1.595.891.806] <39A03CCA0D7D8796> $2024-11-28 21:09:54$ z:/tre_00000001.zpaq

Hello Mr.Corbelli,

Many thanks, this one works :

busybox64.exe sed -i "s/Consolidated/backuparchive/g" Consolidated_00000000_backup.txt

Following the busybox operation, I renamed the multipart backup files to "backuparchive"

60_10j.zip You can try the (not tested) pre-release with -destination, with rename

zpaqfranz consolidate /tmp/theold.zpaq -destination /tmp/renamed.zpaq

and rename-copy

zpaqfranz consolidate /tmp/theold.zpaq  -destination /backup/somewhere_already_present/thebrandnew.zpaq

(the difference is in the output path)

No test for errors (like rename to himself, use only fullpath (not relative) etc)

Hi Mr. Corbelli,

Thanks for your efforts. I managed to compile the code with Msys2 :

g++ -m64 -O3 zpaqfranz.cpp -o zpaqfranz64 -pthread -static -lurlmon

Testing the first option to rename the "Consolidated" archive :

C:\>zpaqfranz64 consolidate C:\Consolidated.zpaq -destination C:\Backuparchive.zpaq
zpaqfranz v60.10j-JIT,-GUI,-L,HW SHA1/2,4,SFX64 v55.1,(2024-11-29)

franz:-destination          C:/Backuparchive.zpaq 0
franz:-noconsole
Renaming to -destination <<C:/Backuparchive.zpaq>>
Copy-Rename .index <<C:/Consolidated_00000000_backup.index>> => <<C:/Backuparchive_00000000_backup.index>> :OK
Copy-Rename <<c:/consolidated_00000001.zpaq>> => <<c:/consolidated_00000001.zpaq>> :OK
0.062s (00:00:00,52.48KB) (all OK)

Only the index file is renamed :

Backuparchive_00000000_backup.index
Consolidated_00000000_backup.txt
consolidated_00000001.zpaq

I'll check in the afternoon, more developing is needed

It is hard to delete the dangling old _backup.txt
