Hi Keith,

Please send an e-mail to customerservices@aiscl.co.uk so that I know where to send them, thank you.

I’m sorry but it appears that the bug report was not received for some reason. I checked the Zen e-mail parameters on their website and they are pretty much as you used, however you did not mention the SMTP host setting, but I’m pretty sure you entered this correctly. Zen suggest using SMTP port 465...

The default pruning in AISBackup is the ‘Advanced pruning’ option, this keeps a number of daily, weekly and monthly backups. You may change this setting by using the Session settings. Manage Backup / Change Backup Job Settings / Session Settings / Select Session Based / Then Keep and choose the numb...

I re-checked the AISBackup code, AISBackup already uses the quickest zip method, it is still slower than using the uncompressed option, but mitigated when the backup job is used again to make a new session as only new and changed files are actually backed up. AISBackup’s performance can be improved ...

Compression level in zip files is set between 0 and 9, where 0 is no compression and 9 is maximum compression. Tests were run using the different compression levels and it was found that using the level 2 gave the best speed vs. compression ratio, albeit 20+ years ago. I am compiling some statistics...

AISBackup already maintains a list of files that should not be compressed, but for some reason did not contain .JPG. The list is maintained in Tools / Do not Compress File List . AISBackup maintains a list of compression stats so can be updated automatically by selecting the Auto Update button, howe...

You have posted the random password, but you cannot use that in AISBackup, you must use the original password you used when you setup the backup job. There is no way to convert the encrypted password back to your original password. You must have set-up the backup to 'don't ask for a backup on restor...

If you make a new backup where only the photos are selected, and leave all other settings to their defaults, does this now work? I’ve never seen this problem before in 24 years. If so on the main AISBackup screen selected (just click it) press * until ‘*** All Debug Mode ***’ is displayed in the cap...

Since making my previous reply I have done some research into cracking zip file passwords and I used a popular password cracker to do some tests. Using a password of 7 characters the password was found within 5 seconds, using the same password with AISBackup’s password encryption method the password...

AISBackup uses zip file encryption, it has an option to make a much longer password than what you supply, i.e. the password itself is one way encrypted. For those concerned about security it is probably best to backup to disks that have been encrypted with BitLocker (or a third party encryption appl...

Hi Hugh, I just checked the source code and there is no folder called 'Transferred' so I'm not sure what this is. I think the safest thing to do is do is to rename the folder to see if anything fails. Does the folder contain AISBackup files? You could also check that these files exist in the backup ...

Hi Hugh

If you can e-mail me the backup job files by using the Help / Bug Report option I should be able to find out which file this is.

Hi Hugh

I looks like AISBackup isn't able to replace some files on the server, this may be because of security settings or the server is holding the files open for write. Is it possible for you to make another backup job that only backs up this failing file for testing?

Barry

Hi Hugh I just backed up a 4.3GB file to A local Synology NAS and that worked without error, the files are split at 4GB. I restored the file to another location on my PC. This may be a timeout issue: There is an option to split files at 2GB instead of the default 4GB, this may be set by using Manage...

In 22 years of AISBackup this has never been reported before, and to be honest I never noticed that the select files for backup uses the 'display name' of a folder (by design) but the actual backup phase uses the real name of the folder (oops). Using the real name of the folder for the backup is a g...
