SOLVED [CPANEL-31980] Error in Restore a Home Directory Backup - @LongLink error

[Denis.v]

Hello.
cPanel v86.0.13.
When executing 'Restore a Home Directory Backup' by a user, if there are files in the archive with a path length longer than 103 (or 108) characters, then we see an error:

• (XID cthts2) The system failed to open the file “/home/username /./@LongLink” for writing because of an error: Permission denied
• (XID k4jy28) The system failed to open the file “/home/username /./@LongLink” for writing because of an error: Permission denied
• ...

After unpacking, total files name (with path) is truncated to a length approximately 103 characters. For example, there was a file "1234567890.php", it became "12345" or "12".
In the file “12345”, the path of this file and the characters “^ @” appear on the first line, for example: /public_html/catalog/controller/checkout/1234567890/1111111111111111/12345678901234567890aaaaaaa/1234567890.php^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@, and the "@LongLink" file is created in the /home/username directory (modify 1970-01-01 03: 00: 00.000000000 +0300, access rights 000), with the path of one of these files inside.
Manual unpacking of archives backup file occurs without any errors.
What is this strange behavior and how to fix it?
Steps for reproduce:
- create file(s) in homedir/public_html with long path (total length more than 104 symbols);
- create backup file (Download a Home Directory Backup) in cPanel Backup;
- Restore a Home Directory Backup.

Had a client have the same issue the other day

Hello,

Thank you for opening a ticket. It looks your ticket spawned an internal case CPANEL-31980. We also created the following article: cPanel-31980 (use your cPanel/manage2/store account to login and view the article)

We'll update here when the internal case has been resolved.

What's happening with this? I had a site down for 10 hours yesterday because of this problem. Thanks to dalem's post I was able to get the site up and running but this problem definitely needs to be fixed. Being able to properly and reliably restore backups is kinda important.

I tried to read the article but when I visit the page linked a full screen login prompt appears. When I try to log-in it tells me my email address or password is wrong. So I try to reset my password but I never get an email with the reset link. Because I never get the email(s), it would imply the email address I was trying to log-in with is incorrect/not in the sytem. So I try to create an account with the email address that apparently isn't on file... only to have the system tell me that my email address is already in use!!!

Long story short, I can't view the article because your website is messed up.
